合成了三种通过分子内或分子间配位稳定的芳基锑和芳基铋阳离子配合物。用TlPF_6处理SbAr_2Cl或BiAr_2Cl（Ar = 2-[（二甲氨基）甲基]苯基，2-（Me_2NCH_2）C_6 H_4）分别得到[SbAr_2][PF_6]（1）或[BiAr_2][PF_6]（2）。通过SbPhCl_2与2当量TlPF_6在过量OP（NMe_2）（3）存在下的反应，制备了通过分子间配位稳定的相关配合物[SbPh_2 {OP（NMe_2）（3）}（2）][PF_6]（5）。化合物1，2和5的X-射线晶体结构进行了描述，在每个新的化合物中的第15族元素中心的配位几何被发现是扭曲的三角双锥。
Three cationic aryl-antimony and -bismuth complexes stabilized by intra- or intermolecular coordination have been prepared. Treatment of either SbAr2Cl or BiAr2Cl (Ar = 2-[(dimethylamino)methyl]phenyl, 2-(Me2NCH2)C6H4) with TlPF6 afforded [SbAr2][PF6](1) or [BiAr2][PF6] (2), respectively. A related complex, [SbPh2{OP(NMe2)(3)}(2)][PF6] (5), stabilized by intermolecular coordination, was prepared via the reaction of SbPhCl2 with 2 equiv of TlPF6 in the presence of an excess of OP(NMe2)(3). The X-ray crystal structures of compounds 1, 2, and 5 are described; the coordination geometry at the group 15 element center in each new compound was found to be distorted trigonal bipyramidal.
