description

Abstract Three dithiocarbamatonickel(II) complexes, [Ni(bzbudtc)2] (1), [Ni(bzbudtc)(PPh3)(NCS)] (2) and [Ni(bzbudtc)(PPh3)(CN)] (3) (where, bzbudtc = the N-benzyl-N-butyldithiocarbamato anion and PPh3 = triphenylphosphine), were prepared. All three complexes were analyzed by UV–Vis, IR and NMR (1H, 13C and 31P) spectra. The 13C NMR spectra of complexes 1–3 show the most crucial thioureide signal at around 200 ppm. A significant deshielding observed for the 31P signals in 2 and 3 reveals the effective bonding of phosphorus to the metal center. Single crystal X-ray analysis of crystals of 1–3 show that all the described complexes exhibit a distorted square planar coordination geometry in the solid state as a result of the small bite angle of the dithiocarbamato ligand. The observed magnitude of deviation out of the mean plane of nickel is in the following order: 1
