A heteronuclear complex of [Mn(H2O)4(CuL)2]2·4H2O 1 (H2L = 2-hydrogen benzaldehydeneglycylglycine) has been synthesized and characterized by IR spectra, TGA, and single crystal X-ray diffraction analysis. The molecule consists of one \textMn(\textH2\textO)42+\text{Mn}{(\text{H}_{2}\text{O})_{4}}^{2+} Mn(H2O)42+ group and two symmetric groups [CuL]? which are connected by carboxylate oxygen atoms. A discrete water hexamer composed of a planar tetrameric water ring and two pendent water molecules acts as a ‘glue’ to assemble adjacent [CuL]? into a two-dimensional structure.
