Abstract
Three new planar Ni(II) dithiocarbamate complexes; [Ni(4-dpmpzdtc)(2)] (1), [Ni(4-dpmpzdtc)(PPh3)(NCS)] (2) and [Ni(bupcbzdtc)(PPh3)(NCS)] (3) (where, 4-dpmpzdtc = 4-(diphenylmethyl)piperazinecarbodithioato anion, bupcbzdtc = N-butyl-N-(4-chlorobenzyl))dithiocarbamato anion and PPh3 = triphenylphosphine) with "NiS4'' and "NiS2PN'' chromophore units were synthesized and characterized by single crystal X-ray structural analysis as well as UV-Vis, IR and NMR (H-1, C-13 and P-31) spectroscopy. For 2, H-1-H-1 COSY spectrum was also recorded. Single crystal X-ray structural analysis of 1-3, reveals a slightly distorted square planar geometry in all three complexes wherein the steric and electronic influence of auxiliary ligands PPh3 and NCS induces change in the bonding parameters of the latter two complexes (especially in 3). Nickel sulfide nanoparticles were produced from complex 1 by solvothermal synthesis. The morphology and a qualitative phase analysis of the nanoparticles are also viewed in the study.
