报道了空间要求较高的卡宾的两个13族配合物1，3-bis(2，6-diisopropylphenyl)imidazol-2-ylidene，(IPR)的合成。[MX3(IPR)]M=Al，X=H；M=In，X=Br；两者都已进行了结构表征。还报道了咪唑盐[IPrH][InBr4]的晶体结构，它是在[InBr3(IPr)]加合物的制备过程中，通过外加水的存在而形成的。介绍了配合物[InBr3(IMES)]的制备方法，IMES=1，3-bis(2，4，6-trimethylpheny)imidazol-2-ylidene，，并对其晶体结构进行了详细分析。此外，还有两种铟。研究了氮供体配体的三溴加合物，即体积较大的重氮丁二烯和奎宁。报道了N，N‘-1，4-bis(2，6-diisopropylphenyl)diazabutadiene三溴化铟和双(奎尼丁)三溴化铟的晶体结构。(C)2002 Elsevier Science B.V.保留所有权利。
The syntheses of two Group 13 complexes of the sterically demanding carbene, 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, (IPr), are reported, vis. [MX3(IPr)] M = Al, X = H; M = In, X = Br; both of which have been structurally characterised. Also reported is the crystal structure of the imidazolium salt [IPrH][InBr4], formed by the presence of adventitious water in the preparation of the [InBr3(IPr)] adduct. The preparation of the complex [InBr3(IMes)], IMes = 1,3-bis(2,4,6-trimethylpheny)imidazol-2-ylidene, is described as are details of its crystal structure analysis. In addition, two indium. tribromide adducts of nitrogen donor ligands, namely a bulky diazabutadiene and quinuclidine have been investigated. The crystal structures of N,N'-1,4-bis(2,6-diisopropylphenyl)diazabutadiene indium tribromide and bis(quinuclidine)indium tribromide are reported. (C) 2002 Elsevier Science B.V. All rights reserved.
