SnCl_4作为有机合成的重要催化剂受到人们的广泛关注.由于SnCl_4衍生的配位化合物中的锡原子具有四配位和六配位的功能而受到人们的重视.已知DMF能与SnCl_4生成确定的SnCl_4·2DMF配合物.我们曾系统地研究了SnCl_4的水合水解产物及常用有机溶剂的溶剂化产物的~(119)Sn核磁共振谱.在用NMR研究SnCl_4与DMF(N,N-二甲基甲酰胺)的相互作用过程中,我们得到了一个新的产物.测定了它的晶体结构[Sn_2Cl_6(μ-OH)_2(DMF)_2]·4DMF.
SnCl_4 has attracted much attention as an important organic synthesis catalyst due to the fact that the tin atom in SnCl_4-derived coordination compounds has the function of tetracoordination and hexacoordination, and it is known that DMF can form SnCl_4 with SnCl_4 · 2DMF complex.We have systematically studied the ~ (119) Sn nuclear magnetic resonance spectrum of hydrated hydrolysates of SnCl_4 and the solvates of common organic solvents.Using NMR to study the interaction between SnCl_4 and DMF (N, N-dimethylmethane Amide), we obtained a new product, and its crystal structure [Sn_2Cl_6 (μ-OH) _2 (DMF) _2] · 4DMF was determined.
