以4,4'-磺酰基二苯甲酸(H2SDBA)和4,4'-二[(1H-咪唑基)甲基]联苯(bimb)为配体,采用水热合成法合成了一种新型的二维镍(Ⅱ)配位聚合物[Ni(SDBA)(bimb)(H2O)2]n(1),其结构经X-射线单晶衍射和元素分析表征。1属单斜晶系,空间群C2/c,晶胞参数a=34.448(11),b=5.563 2(17),c=18.509(6),β=118.830(8)°,V=3 107.4(17)3,Z=4,Dc=1.525 g.cm-3,μ=0.753 mm-1,F(000)=1 480,R1=0.040 8,wR2=0.111 2。1中Ni(Ⅱ)与两个bimb的两个氮原子,两个SDBA2-的两个氧原子和两个水分子的两个氧原子配位,形成一个畸变的八面体几何构型。Ni(Ⅱ)经SDBA2-桥联形成一维波浪状链,链与链之间又通过bimb配体形成二维格子层状结构。
A novel two dimensional Ni(Ⅱ) complex,[Ni(SDBA)(bimb)(H2O)2]n(1),was synthesize by solvothermal reactions of 4,4′-sulfonyldibenzoic acid(H2SDBA) and 4,4′-bis[(1H-imidazol-1-yl)methyl]-biphenyl(bimb).The structure was characterized by X-ray single crystal diffraction and elemental analysis.1 belongs to monoclinic,space group C2/c with a=34.448(11) ,b=5.563 2(17),c=18.509(6),β=118.830(8)°,V=3 107.4(17)3,Z=4,Dc=1.525 g·cm-3,μ=0.753 mm-1,F(000)=1 480,R1=0.040 8,wR2=0.111 2.Ni(Ⅱ) is six-coordinated with slightly distorted octahedral coordination geometry by two N atoms from two bimb,two O atoms from two SDBA2-and two O atoms from two coordinated water molecules.The Ni(Ⅱ) is bridged by the SDBA2-into a wavy chain,which is further linked into grid network by bimb.
