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 Pt^III (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 Pt^III-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-O_sulfate distance is 2.144 (7) Å.
