4N,O2:O3:O3'] dihydrate]Abstract: In the title coordination polymer, {[Mn(C7H3NO4)(H2O)2]·2H2O}n, the MnII ion is coordinated in a distorted octahedral environment by the O atoms of two water molecules, one N and one O atoms of the chelating pyridine-2,3-dicarboxylate (PDC) dianion, and two axial bridging carboxylate O atoms from two adjacent PDC ligands. The fully deprotonated PDC anion acts a 3-bridging ligand, establishing a chain structure along the a axis. These polymeric chains are connected into a three-dimensional framework via several intermolecular O-H
O hydrogen bonds.
