  Dimeric structure of the complex anion [(SnCitr)4Pt(μ-SnCitr)2Pt(SnCitr)4]6− (Citr3− = −OOCCH2C(OH)(COO)−CH2COO−) with two bridging tin atoms obtained by the method of radial distribution functions of atoms in powder samples and in solution

  摘要：

  Using the method of Radial Distribution Functions (RDF) of atoms it has been shown directly that a platinum-tin complex with tin coordinated by citrate ligands is the binuclear platinum anion [(SnCitr)4Pt(mu-SnCitr)2Pt(SnCitr)4]6-. The core of the complex is a platinum cluster wherein each platinum atom is bonded via metal-metal bonds (2.58 angstrom) with six tin atoms situated at the vertices of a slightly distorted octahedron. Two such quasi-octahedrons have a common edge (two of 10 tin atoms are bridges between two platinum atoms) so forming a dimer. The Pt...Pt separation is 3.92 angstrom, i.e. a direct Pt-Pt bond is absent. A model simulation of RDF has allowed us to find the main geometric parameters of the platinum-tin cluster. Citrate ligands coordinate tin atoms in the periphery of the cluster. The structure of the complex anion is the same whether it appears in a potassium salt or in an acid. Solvation in water does not change the diplatinum anion structure.
