杂立方烷[Rh(μ3-I)(C4H4BPh)]4(1)与银盐在乙腈中反应生成不稳定盐[Rh(NCMe)3(C4H4BPh)]BF4(2)。该盐2与六甲苯反应生成芳烃配合物[Rh(C4H4BPh)(HMB)]BF4(3)，并与均三甲苯[Rh(1，3，5-C6H3Me3)(C4H4BPh)]BF4(4)反应。配合物2在真空下失去乙腈，生成聚合盐Catena-[{Rh(μ，η5：η6-C4H4BPh)}BF4]x(5)。通过广角X射线散射实验获得了该聚合物的径向分布函数，深入了解了该聚合物的基本结构特征。当用乙腈处理时，配合物5再生2，而用吡啶处理得到[Rh(Py)3((C4H4BPh)]BF4(6))。从[Rh(μ3-I)(C4H4BPh)]4(1)和相应的甲基硼络合物[Rh(μ3-I)(C4H4BMe)]4(1/1)的CH2Cl2溶液中结晶得到了三核配合物(η5-C4H4BPh)Rh(μ3-I)3RH(μ，η5：η6-C4H4BPh)Rh(η5-C4H4BMe)·CH2Cl2(7)，其中桥联μ，η5：η6-C4H4BPh配体；
The heterocubane [Rh(μ3-I)(C4H4BPh)]4 (1) reacts with Ag+ salts in acetonitrile to give the labile salt [Rh(NCMe)3(C4H4BPh)]BF4 (2). This salt 2 reacts with hexamethylbenzene (hmb) to give the arene complex [Rh(C4H4BPh)(hmb)]BF4 (3), and with mesitylene [Rh(1,3,5-C6H3Me3)(C4H4BPh)]BF4 (4) is obtained. Complex 2 loses acetonitrile under vacuum to produce the polymeric salt catena-[{Rh(μ,η5:η6-C4H4BPh)}BF4]x (5). Insight into the essential structural features of this polymer provided its radial distribution function obtained from a wide-angle X-ray scattering experiment. When treated with acetonitrile, complex 5 regenerates 2 and with pyridine affords [Rh(py)3((C4H4BPh)]BF4 (6). Crystallization from a solution of [Rh(μ3-I)(C4H4BPh)]4 (1) and the corresponding methylborole complex [Rh(μ3-I)(C4H4BMe)]4 (1/1) in CH2Cl2 produces the trinuclear complex (η5-C4H4BPh)Rh(μ3-I)3Rh(μ,η5:η6-C4H4BPh)Rh(η5-C4H4BMe)·CH2Cl2 (7) with a bridging μ,η5:η6-C4H4BPh ligand; complex 7 was characterized by an X-ray structure determ...
