{CH2(PPh2=NSiMe3)(PPh2=S)} （PPh2=S）与相应的二卤化锌ZnCl2和ZnI2反应得到了（亚氨基磷酰）（硫代磷酰）甲烷锌配合物[{(PPh2=NSiMe3)(PPh2=S)CH2}ZnX2] （X = Cl， I）。（亚磷酰）（硫磷酰）甲烷配体作为双齿配体通过氮和硫原子与锌原子配位，形成六元金属环（N-P-C-P-S-Zn）。{CH2(PPh2=NSiMe3)(PPh2=S)}与[Zn{N(SiMe3)2}2]和ZnPh2反应得到（亚磷酰）（硫磷酰）甲烷配合物[{(PPh2=NSiMe3)(PPh2=S)CH}Zn{N(SiMe3)2}]和[{(PPh2=NSiMe3)(PPh2=S)CH}ZnPh]。在这些配合物中，除了磷亚胺氮原子和硫原子与锌原子配位外，还观察到P-C-P桥的甲基碳原子与锌原子之间有长接触。所有新化合物的固态结构均通过单晶x射线衍射确定。
The (iminophosphoranyl)(thiophosphoranyl)methane zinc complexes [{(PPh2=NSiMe3)(PPh2=S)CH2}ZnX2] (X = Cl, I) have been obtained by the reaction of {CH2(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 {CH2(PPh2=NSiMe3)(PPh2=S)} with [Zn{N(SiMe3)2}2] and ZnPh2 resulted in the (iminophosphoranyl)(thiophosphoranyl)methanide complexes [{(PPh2=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.
