Bis[μ-3-(2-hydroxyethyl)-2-methyl-4-oxo-4H-pyrido[1,2-a]pyrimidin-9-olato-κ3N,O:O]bis[aquachloridocopper(II)]

In the dinuclear centrosymmetric copper(II) title compound, [Cu2(C11H11N2O2)2Cl2(H2O)2], each CuII ion has a slightly distorted trigonal-bipyramidal geometry and is coordinated by one N and one O atom from one 3-(2-hydroxyethyl)-2-methyl-4-oxopyrido[1,2-a]pyrimidin-9-olate ligand, another O atom from the second ligand, one water molecule and one Cl atom. The crystal structure involves intermolecular C—H...Cl, O—H...Cl and O—H...O hydrogen bonds
