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) ,β = 99.86(3)°,V = 2424.7(8) 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) ,β = 99.40(3)°,V = 2463.1(9) 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.
