The copper complex, [Cu2(II)(dmpa)2(P-Cl - C6H5COO)2], has been prepared and its structure determined using X-ray crystallography. The dimer is a di-μ2-alkoxo complex which is a five-coordinate copper dimer with unsupported alkoxo bridges. The complex crystallizes in the triclinic space group P-1 with a = 11.384(2), b = 14.636(5), c = 9.609(2) Å, α = 100.07(2), β= 104.33(3), γ = 72.79(2)°, V = 1471.8(7) Å3, and Z = 2. The structure is comprised of discrete binuclear clusters in which the metal atoms are bridged by two alkoxo oxygens of the dmpa- ligands. The Cu - O and Cu - N distances are in good agreement with those found for other copper(II) aminoalcoholato complexes. The Cu⋯Cu distance is 2.9765(6) Å. In the crystal, every two dimeric coordination molecules are combined together by the recognition through intermolecular hydrogen-bonding interactions between the apical water molecule and the non-coordinated O atom from the p-chlorobenzoato ligand, forming a tetramer.
