(3). Znl2 and ZnBr2 react with the silylated phosphaneimines Me3SiNPR3(R = Me, Et) in the presence of NaF at elavated temperatures to give the phosphoraneiminato complexes [ZnI(NPEt3)]4 (4), [ZnBr(NPMe3)]4 (5) and [ZnBr(NPEt3)]4 (6), respectively, which according to the IR spectra and to a crystal structure determination of 5 form heterocubane structures. The corresponding reactions with the more bulky
摘要 以二卤化锌和相应的甲硅烷基化膦亚胺为原料,在CH2Cl2中制备了供体-受体配合物[ZnCl2(Me3SiNP(CH2)4CMe3)]2(1)和[ZnI2(Me3SiNPEt3)]2(2)。2 的热解导致形成 [ZnI2(Me2Si(NPEt3)2)] (3)。在 NaF 存在下,Znl2 和 ZnBr2 与甲硅烷基化磷亚胺 Me3SiNPR3(R = Me, Et) 反应,生成磷亚胺配合物 [ZnI(NPEt3)]4 (4), [ZnBr(NPMe3)]4 (5)和 [ZnBr(NPEt3)]4 (6) 分别根据红外光谱和晶体结构确定 5 形成异立方结构。与体积更大的磷亚胺 Me3SiNP(CH2)4CMe3 的相应反应不会产生锌的磷亚胺络合物。1:空间群 P21/n,Z = 2;-60 °C 时的晶格尺寸:a = 903.3(2),b = 1217.9(3),c = 1591。6(2)
