The cation in [PtPh 2{(py) 3COH}(OH 2)] [NO 3] 2·H 2O has octahedral geometry with a Pt-O bond distance of 2.04(1) Å. The higher trans influence of phenyl than aqua ligands is reflected in the Pt-N bond distances: 2.14(2) and 2.17(1) Å trans to the phenyl groups, and 1.99(2) Å trans to the aqua ligand.
