The (iminophosphoranyl)(thiophosphoranyl)methane zinc complexes [{(PPh 2=NSiMe3)(PPh2=S)CH2}ZnX 2] (X = Cl, I) have been obtained by the reaction of {CH 2(PPh2=NSiMe3)(PPh2=S)} with the corresponding zinc dihalides ZnCl2 and ZnI2. The (iminophosphoranyl)(thiophosphoranyl)methane ligand coordinates as a bidentate ligand through the nitrogen and sulfur atoms to the zinc atom to form a six-membered metallacycle (N-P-C-P-S-Zn). The reaction of {CH 2(PPh2=NSiMe3)(PPh2=S)} with [Zn{N(SiMe3)2}2] and ZnPh2 resulted in the (iminophosphoranyl)(thiophosphoranyl)methanide complexes [{(PPh 2=NSiMe3)(PPh2=S)CH}Zn{N(SiMe3) 2}] and [{(PPh2=NSiMe3)(PPh2=S)CH} ZnPh], respectively. In addition to the coordination of the phosphinimine nitrogen and sulfur atoms to the zinc atom, a long contact between the methine carbon atom of the P-C-P bridge and the zinc atom was observed in these complexes. The solid-state structures of all the new compounds were established by single-crystal X-ray diffraction. [{(PPh2=NSiMe 3)(PPh2=S)CH2}ZnX2] (X = Cl, I), [{(PPh2=NSiMe3)(PPh2=S)CH}Zn{N(SiMe 3)2}], and [{(PPh2=NSiMe3)(PPh 2=S)CH}ZnPh] have been synthesized and structurally characterized. Copyright
