摘 要: 以2-丙基-4,5-咪唑二羧酸(H2pimdc)及2,2’-联吡啶(2,2’-bipy)为配体,在水热的条件下合成了镍的配合物[Ni(Hpimdc)2(2,2’-bipy)].通过X-射线单晶衍射仪测定其结构,结果表明:晶体为单斜晶系,晶胞参数a=23.492(10)nm,b=11.490(5)nm,c=26.171(8)nm,β=127.28(3)°,Z=8;Ni原子为六配位.配合物分子之间通过N-H…O氢键形成一维链,然后再通过C-H…O弱作用连接成三维超分子结构. 2-propyl-4,5-imidazoledicarboxylic acid (Hz pimdc) and 2, 2 '-dipyridine (2, 2 '-bipy) were used as ligands to react with Ni2+ ion to obtain a complex [-Ni (Hpimdc)2 (2,2 '-bipy)-]. The compound has been hydrothermally synthesized and characterized by X-ray single crystal diffraction. The complex crystallizes in monoclinic system, lattice parameters a=23.492(10) nm, b=11.490(5) nm, c=26.171(8) nm, β=127.28(3)°, Z=8. The coordination number of Ni2-+- ion is six. The intermolecular hydrogen bonds N-H...O forms a 1D chain, and these chain linked each other with short contact C-H ... O in the complex result in 3D supramoleeular.
