摘要 在[PPN]Cl存在下,n(InCl3):n(Se(SiMe3)2)=2:1反应生成一个硒桥双核配合物[(Ph3P)2N]2[(InCl3)2(μ-Se)](1),晶体结构中的[(InCl3)2(μ-Se)]2-阴离子部分包含一个角度为102.60(3)°的弯曲In-Se-In链接键。在Cy3PO存在下,n(InCl3):n(Se(SiMe3)2)=2:3反应生成一个新奇的金刚烷类四核配合物[Cy3POH]4[(InCl)4(μ-Se)6](2),配合物2的阴离子[(InCl)4(μ-Se)6]4-包含有6个μ-Se2-桥链接4个[InCl]2+单元,平均In-Se-In键角为99.66(3)°。配合物1和2经X-射线结构分析均含有四面体配位的金属铟。 Interaction of n(InCl3):n(Se(SiMe3)a)=2:1 in the presence of [PPN]Cl gave a selenium bridged dinuclear complex [(Ph3P)2N]2[(InCl3)2(μ-Se)](1). In the crystal structure, the anion [(InCl3)2(μ-Se)]^2- contains a bent In-Se-In linkage with an angle of 102.60(3)°. Reaction of n(InCl3):n(Se(SiMe3)2)=2:3 in the presence of Cy3PO (Cy= cyclohexyl) gave a novel adamantane-like tetranuclear complex [Cy3POH]4[(InCl)4(μ-Se)6] (2). The anion [(InCl)4 (μ-Se)6]^4- of 2 contains six μ-Se^2- bridges connecting four [InCl]^2+ units with an average In-Se-In angle of 99.66(3). Both 1 and 2 were shown by X-ray structures to have tetrahedral coordination of indium.
