A new non-symmetric phosphinito-thiophosphinito POCSP-Ni(II) pincer compound was synthetized and characterized. The molecular structure of [NiCl{C₆H₃-2-(OPPh₂)-6-(SPPh₂)}] (1) was unequivocally determined by single crystal X-ray diffraction analysis, showing the Ni center to be located into a slightly distorted square planar geometry. This compound was used as efficient catalyst in C-S couplings of disulfides with iodobenzenes, exhibiting good activity and selectivity as well as tolerance to different functional groups.
