Description

Monoclinic, P2; R = 0.077 for 1914 unique reflections. Orthorhombic, Ic2a, R = 0.0862 for 718 unique reflections. Both structures are typical Wolffram's salt analogues (WSA's) with infinite chains of planar [Pt(en)2]2+ complex units bridged by bromines. The ligands and the perchlorate counter ions are three-dimensionally ordered presumably because of the strong hydrogen bridges observed. Diffuse sheets appear together with Bragg reflections for kappa-odd layers. The monoclinic modification can be converted into the orthorhombic form by Cu Kα irradiation. (orig./TWO)
