The flexible, multi dentate, heteroelemental, dipodal ligands; bis(2pyridylthio)methane, (PyS)2CH2 (Py = pyridyl = C5H4N), (PymS)2CH2, bis(2pyrimidylthio)methane, and bipyrimidyldisulfide, (PymS)2 (Pym = pyrimidine, C4H3N2), were reacted with a series of copper precursors to determine whether monomeric compounds, cubane clusters or polymeric chains would be obtained. Copper(II) chloride, copper(I) cyanide and copper(I) thiocyanate afforded infinite polymeric chains while copper(I) iodide afforded tetranuclear clusters supported by two ligand molecules.

Synthetic Route of 1111-67-7, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. In an article, authors is Xie, Zhu-Lin, once mentioned the application of Synthetic Route of 1111-67-7, Name is Cuprous thiocyanate,molecular formula is CCuNS, is a conventional compound.

In this work, we report the effects of NNS-thiolate ligands and nuclearity (monomer, dimer) on the stability of iron complexes related to the active site of monoiron hydrogenase (Hmd). A thermally stable iron(II) dicarbonyl motif is the core feature of the active site, but the coordination features that lead to this property have not been independently evaluated for their contributions to the {Fe(CO)2}2+ stability. As such, non-bulky and bulky benzothiazoline ligands (thiolate precursors) were synthesized and their iron(II) complexes characterized. The use of non-bulky thiolate ligands and low-temperature crystallizations result in isolation of the dimeric species [(NNS)2Fe2(CO)2(I)2] (1), [(NPhNS)2Fe2(CO)2(I)2] (2), and [(MeNNS)2Fe2(CO)2(I)2] (3), which exhibit dimerization via thiolato (mu2-S)2 bridges. In one particular case (unsubstituted NNS ligand), the pathway of decarbonylation and oxidation from 1 was crystallographically elucidated, via isolation of the half-bis-ligated monocarbonyl dimer [(NNS)3Fe2(CO)]I (4) and the fully decarbonylated and oxidized mononuclear [(NNS)2Fe]I (5). The transformations of dicarbonyl complexes (1, 2, and 3) to monocarbonyl complexes (4, 6, and 7) were monitored by UV/vis, demonstrating that 1 and 3 exhibit longer t1/2 (80 and 75 min, respectively) than 2 (30 min), which is attributed to distortion of the ligand backbone. Density functional theory calculations of isolated complexes and putative intermediates were used to corroborate the experimentally observed IR spectra. Finally, dimerization was prevented using a bulky ligand featuring a 2,6-dimethylphenyl substituent, which affords mononuclear iron dicarbonyl complex, [(NPhNSDMPh)Fe(CO)2Br] (8), identified by IR and NMR spectroscopies. The dicarbonyl complex decomposes to the decarbonylated [(NPhNSDMPh)2Fe] (9) within minutes at room temperature. Overall, the work herein demonstrates that the thiolate moiety does not impart thermal stability to the {Fe(CO)2}2+ unit formed in the active site, further indicating the importance of the organometallic Fe-C(acyl) bond in the enzyme.

Here, we present a strategy for the realization of p-channel inorganic thin film transistors (TFTs) based on vertically stacked contacts and a copper(i) thiocyanate (CuSCN) semiconductor. The CuSCN semiconductor was generated by a simple low-temperature (ca.100 C) solution-based process. Utilizing the vertical architecture, channel length was determined by the thickness of the CuSCN film. This readily endows transistors with ultrashort channel lengths (<700 nm) to afford delivering drain current greatly exceeding that of conventional planar TFTs. Thus, high normalized transconductance of 0.84 S m?1and current density of 248 mA cm?2can be achieved for CuSCN-based vertical TFTs. To further improve the device's performance, we doped SnCl2into the semiconductor film. By doping SnCl2into CuSCN, shallow acceptor states that could induce additional holes were generated above the valence band maximum. The SnCl2-doped TFTs showed enlarged transconductance and current density values of 1.8 S m?1and 541 mA cm?2, respectively, which are comparable with those of other high performance vertical transistors. The p-channel inorganic TFTs developed in this study can open up exciting opportunities in complementary circuits, display switching, and flexible electronics.

The reactions of stannylated and lithiated amines with coppersalts (halogenides, thiocyanates) lead to amido and imido bridged complexes which contain one to twelve metal atoms. [{Li(OEt2)}2][Cu(NPh2)3] (1) results from the reaction of CuCl with LiNPh2 in the presence of trimethylphosphine. With N(SnMe3)3, CuCl reacts to the donor-acceptor complex [ClCuN(SnMe3)3] (2) that is transformed into the tetrameric complex [{CuN(SnMe3)2}4] (3) by thermolysis. 3 can also be obtained by the reaction of LiN(SnMe3)2 with Cu(SCN)2. While terminally bound in 1, the amido ligand is mu2-bridging between copper atoms in compound 3. The influence of the alkyl amide’s leaving group can be seen from a comparison of the reactivity of Me3SnNHtBu and LiNHtBu, respectively. With Me3SnNHtBu, CuCl2 forms the polymeric compound 1?[Cu16(NH2 tBu)12Cl16] (4) whereas in the case of LiNHtBu with both CuCl and CuSCN, the complex [{CuNHtBu}8] (5) is obtained. The latter contains two planar Cu4N4-rings similar to those in 3. If a mesityl group is introduced at the lithium amide, different products are accessible. Both, CuBr and CuSCN, lead to the formation of [Li(dme)3][Cu6(NHMes)3(NMes)2] (6) whose anion consists of a prismatic copper core with mu2-bridging amido and mu3-bridging imido ligands.

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Synthetic Route of 1111-67-7. Introducing a new discovery about 1111-67-7, Name is Cuprous thiocyanate, The appropriate choice of redox mediator can avoid electrode passivation and overpotential, which strongly inhibit the efficient activation of substrates in electrolysis.

Copper(I) thiocyanate derivatives were prepared by the reaction of CuNCS with pyridine (py) and tertiary monophosphine ligands [PR3 in general; in detail: PPh3, triphenylphosphine, P(4-FPh)3, tris(4-fluorophenyl)phosphine)], as well as the potentially bidentate ligand diphenyl(2-pyridyl)phosphine (PPh2py). Mechanochemical methods were used in some cases to investigate stoichieometries that were not easily accessible by conventional solution syntheses. Three forms of the resulting adducts of CuNCS/PR3/py-base (1:3-n:n) stoichiometry-all containing four-coordinate copper(I) atoms and monodentate N-thiocyanate groups-were confirmed crystallographically. Mononuclear arrays are defined for [(PPh2py)3-n(py)nCuNCS], n = 0, 1, 2, the monodentate thiocyanate being N-coordinated in all; two polymorphs are observed for the n = 2 complex, both crystallizing in monoclinic P21 (Z = 2) cells with similar cell dimensions, but with aromatic components eclipsed about the Cu-P bond in the PPh3 complex, and staggered in the PPh2py complex. Bridging thiocyanate groups are found in the 1:1:1 CuNCS/PPh2py/2-methylpyridine (mpy) and P(4-FPh)3/mpy complexes, wherein centrosymmetric dimers with eight-membered central rings are obtained: [(R3P)(mpy)Cu(NCS)2Cu(PR3)(mpy)], as is also the case in the parent 1:2 CuNCS/PPh2py adduct [(pyPh2P)2Cu(NCS)2Cu(PPh2py)2]. For the 1:1:1 CuNCS/P(4-FPh)3/py and PPh3/Brmpy (Brmpy = 3-bromo-4-methylpyridine) adducts, and, likely, CuNCS/PPh2py/py (1:1:1), single-stranded polymers of the form [?Cu(NCS)(PR3)(py-base)(Cu)?](?|?) with linearly bridging NCS ligands were obtained. Some derivatives, representative of all forms, display medium to strong green to blue luminescence when excited with radiation at 365 nm. The 31P CPMAS NMR spectroscopic data clearly differentiate the inequivalent phosphorus positions within each system, showing a wide range of 1J(31P,63/65Cu) values ranging from 965 Hz for [Cu(NCS)(PPh2py)3] to 1540 Hz for dimeric [(4-FPh)3P(mpy)Cu(NCS)2Cu(P(4-FPh)3)(mpy)], reflecting the large variations in the Cu-P bond length.
