摘　　要：采用水热方法,在120℃温度下选用5-溴间苯二甲酸(H2BIPA)和2,2′-联吡啶(2,2′-bipy)与CuCl2·2H2O分别在NaOH与H2BIPA的物质的量之比为2∶1和3∶1时反应,得到了1个具有零维单核铜结构的配合物[Cu(BIPA)(2,2′-bipy)(H2O)2]·H2O(1)和1个一维链状配位聚合物[Cu3(μ3-BIPA)2(μ-OH)2(2,2′-bipy)2]n(2),并对其结构和磁性质进行了研究。结构分析结果表明2个配合物均属于单斜晶系,分别为P21/c和P21/n空间群。配合物1具有零维单核铜结构,而且这些单核铜单元通过O-H…O氢键作用进一步形成了二维层。而配合物2具有基于三核铜单元的一维链结构。这些一维链通过链间的π-π相互作用进一步形成了二维层。2个配合物的结构差异是由反应中NaOH与H2BIPA的物质的量之比不同造成的。研究表明,配合物2的三核铜单元中相邻铜离子间存在反铁磁相互作用。Zero-dimensional mononuclear copper(Ⅱ)coordination compound and 1D chain copper(Ⅱ)coordination polymer,namely[Cu(BIPA)(2,2′-bipy)(H2O)2]·H2O(1)and[Cu3(μ3-BIPA)2(μ-OH)2(2,2′-bipy)2]n(2),were constructed hydrothermally using H2BIPA(H2BIPA=5-bromoisophthalic acid),2,2′-bipy(2,2′-bipy=2,2′-bipyridine),and copper chloride at the nNaOH∶nH2BIPA(molar ratio)of 2∶1 or 3∶1,respectively.Single-crystal X-ray diffraction analyses reveal that both compounds crystallize in the monoclinic system,space groups P21/c or P21/n,respectively.Compound 1 discloses a discrete monomer structure,which is assembled to a 2D sheet through O-H…O hydrogen bonds.Compound 2 has a chain structure based on Cu3 unit.The chains are further extended into a 2D sheet byπ-πstacking interactions.Structural differences between compounds 1 and 2 are attributed to the different molar ratio between NaOH and H2BIPA.Magnetic studies for compound 2 demonstrate an antiferromagnetic coupling between the adjacent Cu(Ⅱ)centers within Cu3 unit.CCDC:1922559,1;1922560,2.
