The title complex, [RhCl(C(21)H(21)O(3)P)(2)(CO)], is a rhodium analogue to Vaska's complex with para-meth-oxy substituents on the six phosphan-yl-aryl units. Two independent mol-ecules are present in the unit cell, with their metal atoms both located on an inversion centre. This causes the chloride and carbonyl ligands to exhibit a positional disorder in a 0.5:0.5 ratio. The two Rh(I) atoms exhibit a distorted square-planar geometry. There are a few weak intra-molecular C-H⋯X inter-actions (X = O, Cl). Inter-estingly, no significant inter-molecular inter-actions are found between the two independent mol-ecules.
标题配合物[RhCl(C₂₁H₂₁O₃P)₂(CO)]是瓦卡配合物的铑类似物，在六个膦酰基芳基单元上带有对甲氧基取代基。晶胞中存在两个独立的分子，它们的金属原子都位于对称中心上。这导致氯和羰基配体呈现出0.5:0.5比例的位置无序。两个Rh(I)原子呈现出扭曲的平面正方形几何构型。存在一些弱的分子内C-H⋯X相互作用（X = O、Cl）。有趣的是，在两个独立分子之间未发现明显的分子间相互作用。
