The title complexes, [Re2Br2(O2CC3H7)4], (1), and [Re2(O2CC3H7)4Cl2]·2CH3CN, (2), both exhibit paddlewheel structures with four carboxyl-ate ligands bridging two Re(III) atoms. The Re-Re distances are 2.2325 (2) and 2.2299 (3) Å, indicating quadruple bonds between the Re(III) atoms in each complex. Both complexes contain an inversion center at the mid-point of the Re-Re bond. The Re-Br bond [2.6712 (3) Å] in (1) is 0.1656 (6) Å longer than the Re-Cl distance [2.5056 (5) Å] of (2). In (2), the N atom of each co-crystallized aceto-nitrile solvent mol-ecule is nearly equidistant between and in close contact with two carboxyl-ate C atoms.
标题配合物[Re₂Br₂(O₂CC₃H₇)₄]（1）和[Re₂(O₂CC₃H₇)₄Cl₂]·2CH₃CN（2）均呈现出桨轮结构，有四个羧酸酯配体桥连两个Re(III)原子。Re-Re键长分别为2.2325 (2) Å和2.2299 (3) Å，表明每个配合物中Re(III)原子之间存在四重键。两个配合物在Re-Re键的中点处均有一个对称中心。（1）中的Re-Br键[2.6712 (3) Å]比（2）中的Re-Cl键长[2.5056 (5) Å]长0.1656 (6) Å。在（2）中，每个共结晶的乙腈溶剂分子的N原子与两个羧酸酯C原子之间的距离几乎相等且紧密接触。
