Syntheses and Crystal Structures of Two One-dimensional Coordination Polymers Constructed from a Flexible Hinge-like Ligand

摘要

By using the flexible hinge-like ligand 2,2′-bis(3-hydroxy-1,4-naphthoquinone) (H2bhnq), two isomorphous one-dimensional zigzag chain coordination polymers have been obtained. Single-crystal X-ray analyses revealed that the metal centers in these two complexes are distorted octahedra involving four oxygen atoms of two bhnq2- anions, and two oxygen atoms of two DMF molecules situated in trans positions to one another. Crystal data for [Mn(bhnq)(DMF)2]n 1: C26H22MnN2O8, Mr = 545.40, monoclinic, space group C2/c, a = 14.936(3), b = 10.362(2), c = 15.901(3)(A),β = 99.86(3)°, V = 2424.7(8)(A)3, Z = 4, Dc = 1.494 g/cm3, F(000) = 1124, μ = 0.599 mm-1, final GOOF = 1.025, R = 0.0654 and wR = 0.1537. Crystal data for [Cd(bhnq)(DMF)2]n 2: C26H22CdN2O8, Mr = 602.86, monoclinic, space group C2/c, a = 14.839(3), b = 10.493(2), c = 16.034(3) (A),β = 99.40(3)°, V = 2463.1(9)(A)3, Z = 4, Dc = 1.626 g/cm3, F(000) = 1216, μ = 0.941 mm-1, final GOOF = 1.069, R = 0.0358 and wR = 0.0944.
