Aqua(2,2′-bipyrimidine-κ²N,N′)(succinato-κ²O¹,O⁴)copper(II) dihydrate

Abstract

In the crystal structure of the title compound, [Cu(C(4)H(4)O(4))(C(8)H(6)N(4))(H(2)O)]·2H(2)O, the Cu(II) atom is chelated by a 2,2'-bipyrimidine (bpm) ligand and a succinate anion in the basal plane; a water mol-ecule in the apical position completes the slightly distorted square-pyramidal coordination geometry. Another carboxyl-ate O atom from an adjacent complex is located in the opposite apical direction, with a Cu⋯O distance of 2.706 (3) Å, and is not considered as a bridging atom. Extensive O-H⋯O and O-H⋯N hydrogen bonding is present in the crystal structure.
