摘要
By using the flexible hinge-like ligand 2,2'-bis(3-hydroxy-l,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)A3, Z = 4, Dc = 1.494 g/cm^3, 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/cm^3, F(000) = 1216,μ = 0.941 mm^-1, final GOOF = 1.069, R = 0.0358 and wR = 0.0944.
