title: Bis[μ-3-(2-hydroxy-ethyl)-2-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidin-9-olato-κN,O:O]bis[aquachloridocopper(II)].
abstract: In the dinuclear centrosymmetric copper(II) title compound, [Cu(2)(C(11)H(11)N(2)O(2))(2)Cl(2)(H(2)O)(2)], each Cu(II) ion has a slightly distorted trigonal-bipyramidal geometry and is coordinated by one N and one O atom from one 3-(2-hydroxy-ethyl)-2-methyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligand, another O atom from the second ligand, one water mol-ecule and one Cl atom. The crystal structure involves inter-molecular C-H⋯Cl, O-H⋯Cl and O-H⋯O hydrogen bonds.
