Synthesis and structure of di-μ-hydroxo-bis[bis(dimethyl sulfoxide)platinum(II)] perchlorate

“…Therefore O(1')lies 0.2 A out of the best plane. This is similar to the structure of [(NH3)2Pt(OH)zPt(NH3)21-(NOx)~ where the dimeric ion is also planar (Stanko, Hollis, Schreifels & Hoeschele, 1977;Faggiani, Lippert, Lock & Rosenberg, 1977). But it is different from the structure of Bushnell, 1978), which contains a bent hydroxo bridge.…”

Structure of a cyclic hydroxo-bridged PtII trimer with platinum–silver bonds

“…At physiological pH, the hydrolyzed products isolated so far, for which X-ray structural data are available, were shown to contain oligomeric species. The crystal structures of hydroxo-bridged dimers (Faggiani, Lippert, Lock & Rosenberg, 1977a;Stanko, Hollis, Schreifels & Hoeschele, 1977;Lippert, Lock, Rosenberg & Zvagulis, 1978) and trimers (Faggiani, Lippert, Lock & Rosenberg, 1977b, 1978 have been reported. These oligomers are toxic (Rosenberg, 1978) and might be partly responsible for the…”
