| 摘要: 本文报道了1个二重穿插的配位聚合物[Ni2(1,2-bix)2(oba)2(H2O)2]，并对该化合物进行了元素分析、红外和单晶X-射线表征(1，2-bix=1，2-(二亚甲基苯)二咪唑配体，oba=4，4′-氧联苯二甲酸阴离子)。该化合物属于单斜晶系，空间群P21/n，晶胞参数a=1.475 3(5) nm，b=1.684 1(4) nm，c=2.135 6(5) nm，β=102.864(3)°，V=5.173(2) nm3，Z=4，R=0.040 5，wR=0.101 0。在该化合物中，oba 和1，2-bix连接着Ni(Ⅱ)原子形成二维(4，4)网络结构。2个相邻的(4，4)网络相互穿插形成了二重穿插的二维层状结构。O-H…O氢键进一步地稳定了此层状结构。 | |||||||||

| Abstract: A coordination polymer, [Ni2(1,2-bix)2(oba)2(H2O)2] (1) (1,2-bix=1,2-bis(imidazol-1-ylmethyl)benzene and oba=4,4′-oxybis(benzoate)), has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal data: C56H48N8Ni2O12, monoclinic, space group P21/n, a=1.475 3(5) nm, b=1.684 1(4) nm, c=2.135 6(5) nm, β=102.864(3)°, V=5.173(2) nm3, Z=4, R=0.040 5, wR=0.101 0. In complex 1, the central Ni(Ⅱ) atoms are bridged by the 1,2-bix ligands and oba anions to form a two-dimensional (2D) (4,4) network. Two 2D (4,4) networks interpenetrated in a two-fold mode. In addition, the O-H…O hydrogen-bonding interactions further stabilize the network structure of complex 1. CCDC: 818375. | |||||||||
