The zinc derivative of the novel bis(thiophosphinoyl)(thiolate)methanide dianionic ligand [(S)C(PPh2=S)2]2- (3) has been synthesized and structurally characterized. Treatment of [CH2(PPh2=S)2] (1) with dimethyl zinc in refluxing toluene gave air-sensitive [{HC(PPh2=S)2}2Zn] (5) via elimination of me...
