Bis(-5-carboxylato-1-carboxylatomethyl-2-oxidopyridinium)-²O⁵:O¹;²O¹:O⁵-[diaqua(phenanthroline-²N,N')manganese(II)] dihydrate

M.-X. Jiang and Y.-L. Feng

Abstract: The centrosymmetric binuclear title complex, [Mn₂(C₈H₅NO₅)₂(C₁₂H₈N₂)₂(H₂O)₄]·2H₂O, was obtained by the reaction of manganese chloride with 5-carboxy-1-carboxymethyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn^II atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxylato-1-carboxylatomethyl-2-oxidopyridinium ligands and two water molecules, leading to a distorted octahedral MnN₂O₄ environment. Intermolecular O-HO hydrogen bonds link neighbouring molecules into a layer structure parallel to (001).
