A new manganese coordination polymer 1, [Mn(H2O)4(L)]n(ClO4)2n.2nH2O.3nL (L= 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene), has been synthesized and structurally characterized.The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of monoclinic, space group Pn with a = 13.9176(8), b = 15.4754(9), c = 15.9670(9) (A), β =99.5010(10)°, V = 3391.8(3) (A)3, Z = 2, C56H68Cl2MnN16O14, Mr= 1315.10, Dc = 1.288 g/cm3, μ =0.344 mm-1, F(000) = 1374, R = 0.0733 and wR = 0.2035. In the crystal the manganese atom is six-coordinated by two nitrogen atoms from 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene and four oxygen atoms from water molecules, completing an octahedral geometry. The title complex exhibits a novel supramolecular layer architecture sustained by the concurrence of coordination bonds,hydrogen bonds, and π-π stacking interactions.
