Abstract: The ligand N-(2-hydroxy-3-methoxybenzylidene)glycylglycine (H3L), a Schiff base derived from glycylglycine and 3-methoxysalicylaldehyde, was used in the synthesis of a new organic-inorganic coordination complex, [Mn(H2O)6][Cu(C12H11N2O5)]2·6H2O. The MnII atom is located on an inversion center and is coordinated to six water molecules in a slightly distorted octahedral geometry. The CuII atom is chelated by the tetradentate Schiff base ligand in a distorted CuN2O2 square-planar coordination. In the crystal structure, the complex [Mn(H2O)6]2+ cations and the [CuL]- anions are arranged in columns parallel to the a axis and are held together by O-HO hydrogen bonding. Additional hydrogen bonds of the same type further link the columns into a three-dimensional network.
