摘要：

The title compound, [PtCl2(C2H8N2)(4)](HSO4)(4) or [Pt(C2H8N2)(2)][Pt2Cl2(C2H8N2)(2)](HSO4)(4), has a linear chain structure composed 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 c axis. The Cl atom bridging the adjacent Pt atoms is disordered over two sites along the...Cl-Pt-IV-Cl...Pt-II...chain, which lies on a twofold axis. The Pt-IV-Cl and Pt-II...Cl bond lengths are 2.323 (2) and 3.142 (2) Angstrom, respectively. A structural parameter delta=(Pt-IV-Cl)/(Pt-II...Cl), indicating the mixed-valence state of the Pt atom (delta=0.739), shows a good correlation with the data of the intervalence charge-transfer (IVCT) absorption band.
