The adduct of tetra-μ-benzoato-dicopper(II) with urea, [Cu(C7H5O2)2(CH4N2O)]2, is dinuclear. Each Cu atom is displaced by 0.195 (3) Å from the plane of the four benzoato oxygen atoms to which it is bonded. The CuCu distance is 2.633 (2) Å. The average Cu—O(benzoate) distance is 1.964 (3) Å and the Cu—O(urea) bond length is 2.156 (6) Å.
