The title compound, [Pt(C6H6O4)(C12H8N2)]·2H2O, which crystallizes as two independent formula units, has the metal atom in a square-planar geometry defined by two O atoms of the chelating cyclobutane-1,1-dicarboxylate dianion and two N atoms of the chelating 1,10-phenanthroline molecule (r.m.s. deviations of the PtO2N2 units = 0.026 and 0.026 Å). Adjacent complex and water molecules are connected through intermolecular O-HO hydrogen bonds and C-HO, CO [shortest CO distance = 3.140 (5) Å], - [shortest CC distances = 3.234 (6) and 3.347 (6) Å] and Pt [shortest PtC distance = 3.358 (4) Å] interactions into a three-dimensional network.
