以硫酸锌与1,3-二(N-咪唑基甲基)苯(mbix)为原料,用挥发法合成新型二维锌配位聚合物[Zn(mbix)(SO4)].CH3OH(I),其结构经X-射线单晶衍射和元素分析表征。I属正交晶系,空间群Cmc21,晶胞参数a=12.563(5),b=17.122(6),c=8.661(3),V=1862.9(12)3,Z=4,Dc=1.539 g.cm-3,μ=1.464 mm-1,F(000)=888,R1=0.0540,wR2=0.1319。I中Zn2+与两个mbix配体的两个氮原子和两个SO42-配体的两个氧原子配位,形成一个畸变的四面体几何构型。Zn2+经SO24-离子桥联形成一维波浪状链,链与链之间又通过mbix配体形成二维格子层状结构。
A novel zinc coordination polymer [Zn (mbix) (SO4)] was synthesized by volatilization using zinc sulfate and 1,3-bis (N-imidazolylmethyl) benzene as raw materials. Its structure was characterized by X-ray single crystal diffraction and elemental analysis. I is an orthorhombic system with space group Cmc21 with unit cell parameters a = 12.563 (5), b = 17.122 (6), c = 8.661 (3), V = 1862.9 (12) 3, Z = 4, Dc = 1.539 μ = 1.464 mm-1, F (000) = 888, R1 = 0.0540, wR2 = 0.1319. I Zn2 + coordinates with two nitrogen atoms of two mbix ligands and two oxygen atoms of two SO42-ligands to form a distorted tetrahedron geometry. The Zn2 + forms a one-dimensional wavy chain through the SO24- ion bridge, and the two-dimensional lattice layered structure is formed between the chain and the chain through the mbix ligand.
