In the title compound, [RhCl{P(p-FC(6)H(4))(3)}(3)]·CH(3)OH, the Rh atom adopts a distorted square-planar geometry. Rh, Cl and one P atom lie on a mirror plane, as does the solvent molecule. There are two inter-molecular hydrogen bonds, one between the methanol O atom and an aryl H atom (2.51 Å), and one between the Cl atom and the hydr-oxy H atom of methanol [2.34 (3) Å]. The complex precipitates in trace amounts from a reaction between RhCl(cod)(thp) [cod is 1,5-cyclo-octa-diene and thp is tris-(hydroxy-meth-yl)phos-phine] and P(p-FC(6)H(4))(3) under argon in CD(3)OD. Two C(6)H(4)-F units are disordered over two positions; for one the site occupancy factors are ca. 0.53 and 0.47, for the other the values are ca. 0.64 and 0.36. The methyl H atoms of the solvent molecule are disordered across the mirror plane.
在标题化合物[RhCl{P(p-FC₆H₄)₃}₃]·CH₃OH中，铑（Rh）原子呈扭曲的平面正方形几何构型。铑、氯和一个磷（P）原子位于一个镜面平面上，溶剂分子也如此。存在两个分子间氢键，一个在甲醇的氧原子与一个芳基氢原子之间（键长2.51 Å），另一个在氯原子与甲醇的羟基氢原子之间[2.34 (3) Å]。该配合物是在氩气氛围下，RhCl(cod)(thp) [cod为1,5-环辛二烯，thp为三(羟甲基)膦]与P(p-FC₆H₄)₃在CD₃OD中反应时微量沉淀得到的。两个C₆H₄-F单元在两个位置上无序；对于一个而言，位点占有率因子约为0.53和0.47，对于另一个，其值约为0.64和0.36。溶剂分子的甲基氢原子在镜面平面上无序分布。
