A coordination polymer [Mn(IDA)2(H2O)4]n(H2IDA=N-iminodiacetic acid) was synthesized and characterized by single crystal X-ray diffraction. The crystal belongs to the tetragonal system, the space group is P-421C with the crystal cell parameters a=0.81120(8) nm, b=0.81120(8) nm, c=0.96196(4) nm, V=0.6330(1) nm3, Mr=355.17, R=0.0224, wR=0.061. The four carboxylic oxygen atoms of the different N-iminodiacetic acid ligands and two water molecules coordinate to the manganese atom. The manganese atom is in an approximates octahedral coordination sphere. Each carboxylic acid ligand bridges two manganese atoms, forming two zig-zag supramolecular chains. The twisted chains construct a two-dimension layer structure with regularly arranged X-shaped window cavity. The three-dimension supramolecular network is formed by coordination bonds and hydrogen bonds.
