| Abstract | The asymmetric unit of the title compound, (C4H12N2)0.5[Ga(pydc)2]·pydcH2·2H2O, where pydcH2 is pyridine-2,6-dicarboxylic acid, C7H5NO4, contains one half of a centrosymmetric piperazinediium dication, one anion, one uncoordinated pydcH2 molecule and two uncoordinated water molecules, one of which is disordered over two sites in a 1:1 ratio. In the anion, the GaIII ion is coordinated by four O atoms [Ga—O = 1.9706 (16)–2.0494 (15) Å] and two N atoms [Ga—N = 1.9660 (18) and 1.9709 (17) Å] from two pydc ligands in a distorted octahedral geometry. The crystal structure exhibits intermolecular O—H⋯O, N—H⋯O and O—H⋯N hydrogen bonds and π–π interactions [centroid–centroid distances of 3.5359 (13) and 3.6550 (14) Å]. |
