-chloro-[bis(ethylenediamine)platinum(IV)]--chloro] tetrakis(hexafluorophosphate)]Abstract: The structure of the title compound, {[PtII/IVCl(C2H8N2)2](PF6)2}n or [PtII(C2H8N2)2][PtIVCl2(C2H8N2)2](PF6)4, has been redetermined [Matsushita (1993). Synth. Met. 56, 3401-3406] from image-plate data. No superstructure was observed, in contrast to the situation in related compounds. The linear chain structure consists of square-planar [Pt(en)2]2+ and elongated octahedral trans-[PtCl2(en)2]2+ cations (en is ethylenediamine) stacked alternately, bridged by the Cl atoms, along the b axis. The Pt atom is located on an inversion centre and the Cl atom (site symmetry 2) is disordered over two sites, resulting in PtIV-Cl and PtII
Cl bond distances of 2.327 (4) and 3.191 (4) Å, respectively. The ![[delta]](/logos/entities/delta_rmgif.gif)
structural parameter, indicating the mixed-valence state of the Pt atoms, is 0.729.
