Abstract

The asymmetric unit of the title compound, [Ag(2)(C(2)ClF(2)O(2))(2)(C(25)H(22)P(2))(2)], consists of two half-mol-ecules, each Ag(I) ion lying on a center of symmetry. In each complete mol-ecule, two bis-(diphenyl-phosphino)methane ligands bridge two Ag(I) ions, which are further coordinated by one chloro-difluoro-acetate ligand, giving T-shaped geometries and short intra-molecular Ag⋯Ag distances of 3.1078 (6) and 2.9950 (6) Å. In one mol-ecule, the unique -CF(2)Cl group is rotationally disordered over two sites with approximate occupancies of 0.53 and 0.47 for the major and minor components, respectively.

摘要

标题化合物[Ag₂(C₂ClF₂O₂)₂(C₂₅H₂₂P₂)₂]的不对称单元由两个半分子组成，每个Ag(I)离子位于对称中心。在每个完整分子中，两个双（二苯基膦基）甲烷配体桥连两个Ag(I)离子，它们进一步由一个氯二氟乙酸酯配体配位，形成T形几何构型，分子内Ag⋯Ag短距离分别为3.1078 (6) Å和2.9950 (6) Å。在一个分子中，独特的-CF₂Cl基团在两个位置上发生旋转无序，主要和次要组分的占有率分别约为0.53和0.47。
