A new metal-organic complex [Mn2(PDC)2(bipy)2(H2O)2] (H2PDC = 2,4-pyridine-dicarboxylic acid, bipy = 2,2′-bipyridine) 1 has been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG and single-crystal X-ray diffraction. The compound crystallizes in triclinic, space group P1 with a = 7.376(3), b = 9.990(4), c = 11.950(5) , α = 75.217(5), β = 78.052(5), γ = 70.655(5)o, V = 796.0(5) 3, C34H26Mn2N6O10, Mr = 788.49, Dc = 1.645 g/cm3, μ(MoKα) = 0.866 mm-1, F(000) = 235, Z = 1, the final R = 0.0425 and wR = 0.0700 for 1971 observed reflections (I > 2σ(I)). In the crystal structure, the manganese atom is six-coordinated by two carboxylate oxygen atoms from two different PDC ligands, one aqua ligand, and three nitrogen atoms from 2,2′-bipy and PDC ligands, giving a distorted octahedral geometry. It exhibits a three-dimensional supramolecular network defined by O–H···O hydrogen-bonding interactions.
