Abstract

In the title compound, [Cu(2)(C(8)H(4)BrO(4))(4)(C(16)H(20)N(4))(H(2)O)(2)], slightly distorted square-planar-coordinated Cu(II) ions are bound by one aqua ligand and two monodentate 3-bromo-5-carb-oxy-benzoate anions, and linked into a centrosymmetric dinuclear mol-ecule by a bridging 1,4-bis-(pyridin-4-ylmeth-yl)piperazine (4-bpmp) ligand. In the crystal, mol-ecules are connected into a supra-molecular two-dimensional network parallel to (131) via O-H⋯O hydrogen bonds involving the aqua ligands and 3-bromo-5-carb-oxy-benzoate carboxyl-ate groups.
