摘要
The self-assembly reactions of M^ⅡCl2 （M = Ni, Co） with the flexible bix ligand [bix = 1,4-bis（imidazole-1-ylmethyl）benzene] yielded a 2D network [N^Ⅲ（bix）2Cl2]n 1 and a 1D chain [Co^Ⅱ（bix）Cl2]n 2. Their crystal structures have been determined by X-ray single-crystal diffraction analysis. Complex 1 characters a two-dimensional grid-type structure and crystallizes in monoclinic, space group P21/c with a = 7.7231（7）, b = 12.7787（9）, c = 13.9374（13）A, β = 105.419（4）°, C28H28Cl2N8Ni, Mr = 606.19, Ζ = 2, V = 1326.0（2）A^3, Dc = 1.518 g/cm^3, μ = 0.969 mm^-1, F（000） = 628, R = 0.0429 and wR = 0.0783 for 2503 observed reflections （Ⅰ〉 2σ（Ⅰ））. Compound 2 is a one-dimensional chain and crystallizes in orthorhombic, space group Pbca with a = 11.3696（6）, b = 10.2128（6）, c = 14.4943（9） （A）, C14H14Cl2CoN4, Mr = 368.12, Z = 4, V = 1683.01（17）A^3, Dc = 1.453 g/cm^3, μ = 1.334 mm^-1, F（000） = 748, R = 0.0317 and wR = 0.0800 for 1778 observed reflections （Ⅰ〉 2σ（Ⅰ））. Magnetic properties of the title complexes were also investigated.
