Abstract
The reaction of bis(diphenylglyoximato)platinum(IV) diiodide with AgClO4 in benzene yields red brown needles of the compound bis(diphenylglyoximato)platinum(III) perchlorate (A) and crystals of bis(diphenylglyoximato)platinum(III) perchlorate which contains additionally between one and one and a half moles of benzene per formula unit (B). Both compounds are highly hygroscopic and instantaneously change their color to black-green in a humid atmosphere. Crystals of A are tetragonal, a = 20.325(2), c - 6.519(4) Å, space group D8 4h-P4/ncc, Z = 4. The structure consists of stacks of [Pt(dpg)2]+ cations with equidistant Pt-Pt separations of 3.259(4) Å. The Perchlorate ions are disordered in channels formed by the cation columns. Crystals of B are triclinic, a = 14.29(3), b = 13.54(2), c -10.34(3) Å, a = 85.2(2), β = 113.2(2), γ = 93.9(2)°.Keywords
