The title compound, Cu(C(3)F(5)O(2))(C(3)H(9)OP)(4), comprises a cationic Cu(II) complex and a disordered penta-fluoro-propionate counter-ion. The metal atom has a distorted square-pyramidal coordination environment formed by four O atoms originating from trimethyl-phosphine oxide mol-ecules and the remaining one belonging to the monodentate penta-fluoro-propionate anion, which is situated in the basal plane of the pyramid. The mol-ecules are held together in the crystal by a net of weak C-H⋯O and C-H⋯F hydrogen bonds. The counter anion is disordered over two sets of sites in a 0.629 (5):0.371 (5) ratio.
标题化合物Cu(C₃F₅O₂)(C₃H₉OP)₄由一个阳离子Cu(II)配合物和一个无序的五氟丙酸根抗衡离子组成。金属原子具有扭曲的四方锥配位环境，由四个来自三甲基氧化膦分子的O原子和另一个属于单齿五氟丙酸根阴离子的O原子构成，该阴离子位于锥体的底面。分子通过弱的C-H⋯O和C-H⋯F氢键网络在晶体中结合在一起。抗衡阴离子在两组位置上无序分布，比例为0.629 (5):0.371 (5)。
