Extensive chemical, spectrophotometric, and x-ray structural studies have shown that trivalent rhenium is strongly homophilic-that is, it tends to form bonds to other Re(111) atoms-and it forms at least three different series of ReX(4)(n-) complexes. The mononuclear, square complex, ReBr(4), adds two water molecules to give trans-ReBr(4)(H(2)O)(2). The binuclear complexes Re(2)Cl(8) and Re(2)Br(8) have strong Re-Re bonds, unsupported by halide bridges. The trinuclear species, Re(3)X(12) or Re(3)X(9)L(3), contain the triangular Re(3)X(9) clusters. Use of ReCI(3) appears always to lead directly to products containing Re(3)Cl(9); this unit exists in ReCl(3) itself and does not appear to be kinetically labile. The Re(2)X(8) ions are obtained by reduction of ReO(4)(-) in aqueous HCl or HBr. Salts of ReBr(4)(H(2)O)(2) can be obtained directly from solutions of ReBr(3) in HBr along with numerous other compounds, some containing trinuclear clusters.
广泛的化学、分光光度和 X 射线结构研究表明，三价铼具有强烈的同嗜性，也就是说，它倾向于与其他 Re(111) 原子形成键，并形成至少三种不同系列的 ReX(4)(n-) 配合物。单核、正方形配合物 ReBr(4) 添加两个水分子生成反式-ReBr(4)(H(2)O)(2)。双核配合物 Re(2)Cl(8) 和 Re(2)Br(8) 具有很强的 Re-Re 键，没有卤素桥的支撑。三核物种 Re(3)X(12) 或 Re(3)X(9)L(3) 含有三角形 Re(3)X(9) 簇。使用 ReCI(3) 似乎总是直接导致含有 Re(3)Cl(9)的产物；该单元存在于 ReCl(3) 本身，似乎不具有动力学不稳定性。Re(2)X(8) 离子通过在盐酸或氢溴酸中的 ReO(4)(-) 还原得到。ReBr(4)(H(2)O)(2) 的盐可以直接从 ReBr(3)在 HBr 中的溶液中获得，同时还可以获得许多其他化合物，其中一些含有三核簇。
