Abstract: In the crystal structure of the title compound, [Cu(C₄H₄O₄)(C₈H₆N₄)(H₂O)]·2H₂O, the Cu^II atom is chelated by a 2,2'-bipyrimidine (bpm) ligand and a succinate anion in the basal plane; a water molecule in the apical position completes the slightly distorted square-pyramidal coordination geometry. Another carboxylate O atom from an adjacent complex is located in the opposite apical direction, with a CuO distance of 2.706 (3) Å, and is not considered as a bridging atom. Extensive O-HO and O-HN hydrogen bonding is present in the crystal structure.
