Abstract
The structure of the title complex, [ReBr(C(13)H(19)OP)(CO)(3)], displays a facial coordination of the three CO ligands and a κ(2)O,P coordination mode of the 2-diisopropyl-phosphino-benzaldehyde ligands. The Re-C bond distance for the CO ligand trans to the P atom is, due to its trans influence, elongated to 1.943 (3) Å, showing that this CO ligand is more weakly bound to the Re centre than the other two.
摘要
标题配合物[ReBr(C₁₃H₁₉OP)(CO)₃]的结构显示出三个CO配体的面式配位以及2-二异丙基膦基苯甲醛配体的κ²O,P配位模式。由于P原子的反位影响，与P原子反位的CO配体的Re-C键长延长至1.943(3) Å，这表明该CO配体与Re中心的结合比其他两个CO配体更弱。
