Organotin(IV) diphenylmonothiophosphinates, RnSn(OSPPh2)4-n (R Me, nBu, Bz, Ph, Cy; n = 2 and 3) have been synthesized in good yields by reactions of organotin halides with ammonium diphenylmonothiophosphinate. The compounds have been characterized by infrared and NMR spectra, and two representative compounds were also studied by 119mSn-Mössbauer spectroscopy. The structure of bis(diphenyimonoth
通过有机卤化物与二苯基单硫代次膦酸铵的反应以高收率合成了有机锡(IV)二苯基单硫代次膦酸根,R n Sn(OSPPh 2)4- n(RMe,n Bu,Bz,Ph,Cy; n = 2和3)。 。该化合物已通过红外和NMR光谱进行了表征,还通过119mSn -Mössbauer光谱学研究了两种代表性化合物。双(二苯甲酰基单硫代膦酸酯基)二甲基锡(IV),Me 2 Sn(OSPPh 2)2的结构通过X-射线衍射确定了Sn,Sn弱的Sn·S相互作用形成了聚合物链结构,其中锡原子表现出三角双锥体的几何形状。配体主要通过氧原子连接到锡上。
