Abstract

The reactions of NiCl2·6H2O with the thiolate ligands HSC5H3N-3-SiMe3, HSC6H4-2-PPh2 and HSC6H3- 6-SiMe3-2-OPPh2 yield the planar mononuclear species [Ni(SC5H3N-3-SiMe3)2], [Ni(SC6H4-2-PPh2)2] and [Ni(SC6H3-6-SiMe3-2-OPPh2)2], respectively. The complexes are electrochemically active, displaying Ni(II)/Ni(III) oxidation processes in the high potential range common to most synthetic Ni(II) complexes.
