Abstract

The title compound, [Pt2 IIIC5H 10NO)2(SO4)2(C10H 8N2)2] - 4H2O, is the first reported example of a complex in which an amidate-bridged Pt(bpy) dimer is stabilized in the oxidation level of PtIII (bpy is 2,2′-bipyridine). The asymmetric unit consists of one half of the formula unit with a twofold axis passing through the center of the dimer. The intradimer PtIII-Pt III bond distance [2.5664 (6) Å] is comparable to those reported for α-pyridonate-bridged cis-diammineplatinum(III) dimers [2.5401 (5)-2.5468 (8) Å; Hollis & Lippard (1983). Inorg. Chem. 22, 2605-2614], in spite of the close contact between the bpy planes within the dimeric unit. The axial Pt-Osulfate distance is 2.144 (7) Å.
