The reaction of 1,3‐dimercaptobenzene with iPr2PCl in the presence of the base NaH, furnishes the symmetric ligand [C6H4‐1,3‐(SPiPr2)2] (1a). The direct reaction of this ligand as well as of the literature‐known nonsymmetric ligand [C6H4‐1‐(SPiPr2)‐3‐(OPiPr2)] (1b) with NiCl2 affords the symmetric bis(thiophosphinito) PSCSP pincer complex [C6H3‐2,6‐(SPiPr2)2}NiCl] (2a) as well as the phosphinito–thiophosphinito
