μ-Terephthalato-bis[aquachloro(1,10-phenanthroline)copper(II)]

In the centrosymmetric title compound, [Cu2(C8H4O4)Cl2(C12H8N2)2(H2O)2], each Cu atom is surrounded by an O atom from a terephthalate dianion, a water mol­ecule, a Cl atom and the N atoms from a 1,10-phenanthroline heterocycle in an octahedral arrangement. The terephthalate dianion, which functions as a bridge between two Cu atoms, lies on a special position of \overline 1 site symmetry.
