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。
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.
