Catena-[bis(o-aminobenzoato-kappa(3) N,O:O)Mn(II)]

In the title complex, [C14H12MnN2O4], the Mn(II) cation octahedrally coordinated by two N and two 0 atoms from two o-aminobenzoate ligands and two O atoms from another two o-aminobenzoate ligands. The carboxylate groups of two o-aminobenzoate anions coordinate to the Mn(II) cation in a monodentate manner, whereas the other two o-aminobenzoate anions chelate the Mn(II) cations through the O-atom of the carboxylate group and the N-atom of the amino group. This complex adopts the syn-anti carboxylate bridging mode with the conformation syn(eq)-anti(eq). The title complex is a two-dimensional coordination polymer based on an infinite Mn-O-C-O-Mn chain. There is hydrogen bond interaction within the two dimensional network. The adjacent two-dimensional network is packed only by Van der Waals interactions
