The reaction of Kpmf (pmf = anion of N,N?-bis(pyrimidyl-2-yl) formamidine, Hpmf) with CuSCN afforded the complexes K[Cu4(pmF) 3(SCN)2], 1, and Cu4(pmf)4, 2. Reaction of 1 with [(n-Bu)4N]PF6 in THF gave the complex [(n-Bu)4N][Cu4(pmf)3(SCN)2], 3. Their structures were characterized by X-ray crystallography. Complexes 1 and 3 are the first linear tetranuclear complexes containing only Cu(I) atoms, while complex 2 is cyclic. The four Cu(I) atoms of complexes 1 and 3 are helically bridged by three tetradentate pmf- ligands. The [Cu 4(pmf)3(SCN)2]- anions of 1 show weak interactions with adjacent [K(THF)5]+ cations through the sulfur atoms, forming infinite chains which are subjected to a series of intermolecular pi-pi interactions. In complex 2, the pmf- ligands are coordinated to the copper atoms in bidentate fashion through the two central amine nitrogen atoms, leaving the pyrimidine nitrogen atoms uncoordinated. Unexpected fluxional behaviors were observed for complexes 1 and 3 in solution. By the DNMR analysis, the free energy of activation (DeltaGc?) for the exchange is 12.8 kcal mol-1 at 278 K (Tc), and the rate constant of exchange (Kc) is 470 s-1 for 1. The DeltaGc? and Kc are 12.6 kcal mol-1 at 273 K and 433 s-1, respectively, for 3. The Royal Society of Chemistry 2005.

Thirty-two aryl-substituted 2-benzothiazolamines have been tested for their ability to modulate sodium flux in rat cortical slices. A QSAR analysis, applied to these derivatives, showed a trend toward increasing potency as sodium flux inhibitors with increasing lipophilicity, decreasing size, and increasing electron withdrawal of the benzo ring substitutents. Additionally, 4- or 5-substitution of the benzo ring was found to decrease potency. The combination of increased lipophilicity, small size, and electron withdrawal severely limited which groups were tolerated on the benzo ring, thus suggesting that the optimal substitution patterns have been prepared within this series. Nine of these compounds were potent inhibitors of veratridine-induced sodium flux (NaFl). These nine compounds also proved to be anticonvulsant in the maximal electroshock (MES) assay. Fourteen additional 2-benzothiazolamines demonstrated activity in the MES screen, yet exhibited no activity in the NaFl assay. These derivatives may be interacting at the sodium channel in a manner not discernible by the flux paradigm, or they may be acting by an alternative mechanism in vivo.

Ionic liquids (ILs) coupled with Ag+ or Cu+ salts to form a new kind of reactive absorbent have been studied to separate light olefin from paraffin recently. In this work, we prepared two halogen-free alkylimidazolium thiocyanate ILs with cheaper cuprous thiocyanate, i.e., [Bmim]SCN-CuSCN and [Emim]SCN-CuSCN (Bmim, 1-butyl-3-methylimidazolium; Emim, 1-ethyl-3-methylimidazolium) and investigated their absorption capability for propylene, propane and mixture of both at 1-7 bar and 298-318 K. The effects of operating parameter including cation nature, temperature, pressure, Cu+ concentration and reuse of absorbent were investigated. Propylene shows a chemical absorption while propane does a physical one, and increasing Cu+ concentration effectively improves the absorption capability for propylene and the selectivity of propylene/propane. [Bmim]SCN-CuSCN has higher absorption capability and selectivity for propylene than [Emim]SCN-CuSCN, e.g., [Bmim]SCN-CuSCN-1.5 M can absorb 0.12 mol of propylene per liter while 0.012 mol of propane per liter at 1 bar and 298 K, with a selectivity of 10, which is comparable to some other ILs-Ag+ salts and better than pure ILs. Such absorbents can be regenerated through temperature and pressure swing without remarkable activity loss. This work shows that alkylimidazolium thiocyanate ILs with Cu+ salts are promising reactive absorbents to separate propylene from propane.

The crystal structure of the [Cu(NCS)-(C4H4N 2)]n was investigated. Each Cu atom was coordinated by one N atom of one pyridazine ligand and by one N and two S atoms of three symmetry-related thiocyanate anions within a distorted tetrahedron in the above compound. The compound was prepared by the reaction of CuSCN and pyridazine in acetonitrile in a teflon-lined steel autoclave at 373 K. It was observed that only one N atom of the pyridazine ligand was involved in Cu coordination. It was shown that the Cu atoms were connected via the thiocyanate anions, forming layers parallel to the ab plane.

Treatment of an acetonitrile solution of CuCN with methylcycloarsoxane (CH3AsO)n at 110C affords the coordination polymer ?3[CuCN{cyclo-(CH3AsO)4}] (1), in which infinite CuCN zigzag chains are linked by mu-As1,As 3 cyclotetramers (CH3AsO)4 into an open 3-D framework. Under similar solvothermal conditions, reaction of CuSCN with (CH3AsO)n in the presence of KSCN leads to metal-mediated ring expansion of the cycloarsoxane to yield the complex ? 1[{K[cyclo-(CH3AsO)5]2}Cu(NCS) 2] (2). This contains discrete [Cu(NCS-kappaN)2{cyclo- (CH3AsO)5kappaAs}2]- anions that bridge kappa10O coordinated potassium cations into infinite chains.

The title compounds NH4[Cu(S2CNH2) 2]·H2O (A) and CuS2CNH2 (B) were prepared from aqueous alcoholic solutions by reaction of ammoniumdithiocarbamate with copper sulfate in presence of excess cyanide as reductive. (A) crystallizes in the orthorhombic space group C2221 (No. 20) with a = 8.9518(6), b = 9.6414(6) and c = 10.6176(8) A, Z = 4. (B) crystallizes in the orthorhombic space group P212 121 (No. 19) with a = 5.9533(4), b = 6.6276(4) and c = 9.4834(5) A, Z = 4. In the crystal structure of (A) copper has a tetrahedral surrounding of four monodentate dithiocarbamate ligands. These structural units form 2D nets stacked along [001]. Staggered chains consisting of H2O and NH4+ penetrate the crystal structure along [001] yielding additional coherence via hydrogen bonds. The crystal structure of (B) comprises a three-dimensional tetrahedral framework of CuS 4 units exclusively linked by vertices. The arrangement is reminiscent of a filled beta-cristobalite structure with the dithiocarbamate ligands extending into the hollow spaces. Thermal decomposition precedes stepwise finally giving Cu2S in each case.
