A new copper(II) di-μ2-carboxylato bridged dinuclear complex: [Cu(oda)phen]2 · 6H2O (oda = oxydiacetate, phen = phenanthroline)

A new dinuclear complex [Cu(oda)(1,10-phen)] · 3H2O (oda = oxydiacetate dianion, 1,10-phen = 1,10-phenanthroline) was synthesized and structurally characterized. The complex is centrosymmetric with a Cu2O2 core and a Cu-Cu distance of 3.417(2) Å. Each copper atom resides in a CuN2O4 octahedral environment. Variable-temperature magnetic susceptibility (2-300 K) shows weak ferromagnetic interactions with J = +3.3 cm−1. The intramolecular exchange coupling constant was calculated by the DFT-BS methodology.
