The title rhodium Vaska-type complex, trans-[RhCl{P(C(6)H(11))(2)(C(6)H(4)-4-C(3)H(7))(2)}(2)(CO)], crystallizes with an accompanying acetone solvent mol-ecule. The metal atom shows a distorted square-planar coordination environment with selected important geometrical parameters of Rh-P = 2.3237 (6) and 2.3253 (6) Å, Rh-Cl = 2.3724 (6) Å, Rh-C = 1.802 (2) Å, P-Rh-P = 173.42 (2)° and Cl-Rh-C = 179.13 (7)°. Effective cone angles for the two P atoms are 165 and 161°, respectively. Both isopropyl groups and the acetone mol-ecule are disordered with occupancy values of 0.523 (5):0.477 (5), 0.554 (8):0.446 (8) and 0.735 (4):0.265 (4), respectively. The crystal packing is stabilized by weak C-H⋯O and C-H⋯Cl contacts.
标题铑瓦萨型配合物反式-[RhCl{P(C₆H₁₁)₂(C₆H₄ - 4 - C₃H₇)₂}₂(CO)]与一个伴随的丙酮溶剂分子一起结晶。金属原子呈现出扭曲的平面正方形配位环境,铑 - 磷的选定重要几何参数为2.3237 (6) 和2.3253 (6) Å,铑 - 氯为2.3724 (6) Å,铑 - 碳为1.802 (2) Å,磷 - 铑 - 磷为173.42 (2)°,氯 - 铑 - 碳为179.13 (7)°。两个磷原子的有效锥角分别为165°和161°。两个异丙基和丙酮分子均无序,占有率值分别为0.523 (5):0.477 (5)、0.554 (8):0.446 (8) 和0.735 (4):0.265 (4)。晶体堆积通过弱的C - H⋯O和C - H⋯Cl接触得以稳定。
