Hexaaquamanganese(II) bis{[N-(3-methoxy-2-oxidobenzylidene)glycylglycinato]copper(II)} hexahydrate

L.-W. Lei, Y.-Z. Jiang and Y. Zou

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 Mn^II atom is located on an inversion center and is coordinated to six water molecules in a slightly distorted octahedral geometry. The Cu^II 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.
