摘要
采用水热方法合成出一种新型的间硝基苯甲酸稀土配位聚合物[Nd2(C7H4O4N)7H2O]n,并通过元素分析、红外光谱、X射线单晶结构分析对该配位聚合物进行了表征.标题配位聚合物的晶体属于三斜晶系,P1空间群,晶胞参数a=0.984 8(2)nm,b=1.131 4(2)nm,c=1.366 3(3)nm,α=69.22(3),°β=82.48(3)°,γ=82.21(3)°,V=1.404 5(5)nm3,Dc=1.806 g/cm3,Z=1.结构分析表明:标题化合物是由稀土金属Nd(Ⅲ)和间硝基苯甲酸组成的配位聚合物,此聚合物通过Ln—O—C—O—Ln形成无限一维链状结构,进一步又通过分子间氢键连接形成复杂的三维氢键网络结构.
A new coordination polymer [Nd2(C7H4O4N)7(H2O)4]n was synthesized hydrothermally.It was characteristic by elemental analysis,IR spectroscopy and single-crystal X-ray diffraction.The crystal belongs to triclinic system,space group P1.The cell parameters are as follows: a=0.984 8(2)nm,b=1.131 4(2)nm,c=1.366 3(3)nm,α = 69.22(3)°,β=82.48(3)°,γ=82.21(3)°,V=1.404 5(5)nm3,Dc= 1.806 g/cm3,Z=1.The structure of the complex reveals that the title complex is constructed by lanthanide Nd(Ⅲ) and m-nitrobenzoic acid ligand.The infinite 1D Ln—O—C—O—Ln polymeric chains are connected into a complicated 3D H-bonding framework through numerous intermolecular hydrogen bonds.
