Reaction of copper(II) thiocyanate with pyrimidine leads to the formation of the new ligand-rich 1:2 (1:2 = ratio metal salt to ligand) copper(II) compound [Cu(NCS)2(pyrimidine)2]n (1). Its crystal structure was determined by X-ray single crystal investigations. It consists of linear polymeric chains, in which the Cu2+ cations are mu-1,3 bridged by the thiocyanato anions. The pyrimidine ligands are terminal N-bonded to the Cu2+ cations, which are overall octahedrally coordinated by two pyrimidine ligands and two N-bonded as well as two S-bonded thiocyanato anions. Magnetic measurements were preformed yielding weak net ferromagnetic interactions between adjacent Cu2+ centers mediated by the long Cu-S distances and/or interchain effects. On heating compound 1 to approx. 160 C, two thirds of the ligands are discharged, leading to a new intermediate compound, which was identified as the ligand-deficient 2:1 copper(I) compound [(CuNCS)2(pyrimidine)]n by X-ray powder diffraction. Consequently, copper(II) was reduced in situ to copper(I) on heating, forming polythiocyanogen as byproduct. Elemental analysis and infrared spectroscopic investigations confirm this reaction pathway. Further investigations on other ligand-rich copper(II) thiocyanato compounds clearly show that this in situ thermal solid state reduction works in general. The Royal Society of Chemistry 2009.

Reaction of 2-(2?-pyridyl)benzoxazole (2-PBO) or 2-(4?-pyridyl)benzoxazole (4-PBO) ligands with CuSCN afforded two thiocyanate copper (II) complexes, Cu(2-PBO) (SCN)2 (1) and Cu(4-PBO)2(SCN)2 (2), have been characterized by elemental analysis, UV?Vis, IR spectra and single-crystal X-ray diffraction. The structural analysis reveals that although the structures of complexes 1?2 are both four coordinated and show plane quadrilateral structure, the distorted of complex 1 is greater than 2. The cyclic voltammogram of complexes 1?2 represent quasi-reversible Cu2+/Cu+ pairs. The superoxide radical scavenging test in vitro showed that complex 1?2 had significant antioxidant activity on superoxide radicals, and the activity of complex 2 was higher than that of 1. This may be due to the structure of complex 2 being closer to the Cu, Zn-SOD.

Copper(ii) and copper(i) complexes of a newly designed and crystallographically characterized Schiff base (HL) derived from rhodamine hydrazide and cinnamaldehyde were isolated in pure form formulated as [Cu(L)(NO3)] (L-Cu) (1) and [Cu(HL)(CH3CN)(H2O)]ClO4 (HL-Cu) (2), and characterized by physicochemical and spectroscopic tools. Interestingly, complex 1 but not 2 offers red fluorescence in solution state, and eventually HL behaves as a Cu(ii) ions selective FRET based fluorosensor in HEPES buffer (1 mM, acetonitrile-water: 1/5, v/v) at 25 C at biological pH with almost no interference of other competitive ions. The dependency of the FRET process on the +2 oxidation state of copper has been nicely supported by exhaustive experimental studies comprising electronic, fluorimetric, NMR titration, and theoretical calculations. The sensing ability of HL has been evaluated by the LOD value towards Cu(ii) ions (83.7 nM) and short responsive time (5-10 s). Even the discrimination of copper(i) and copper(ii) has also been done using only UV-Vis spectroscopic study. The efficacy of this bio-friendly probe has been determined by employing HL to detect the intercellular distribution of Cu(ii) ions in HeLa cells by developing image under fluorescence microscope.
