Nickel(II) cyclohexylethyldithiocarbamate complexes with monodentate P-donor ligands in the coordination sphere

Abstract

A series of new Ni(II) dithiocarbamate compounds of the composition [NiX(cetdtc)(PR3)] (X = Cl, Br, I, NCS; cetdtc = cyclohexylethyldithiocarbamate; R = phenyl, n-butyl) has been synthesized. All the isolated complexes have been characterized by elemental analysis, IR and UV/VIS spectroscopy, 31P{1H}-NMR spectroscopy, thermal analysis, magnetochemical and conductivity measurements. On the basis of the results of the physico-chemical study, all complexes are diamagnetic, non-electrolytes, with a square-planar NiS2PX chromophore.
