摘要
采用水热法合成了新的配合物[Ni(H2O)6].[Ni2(phen)2(BTC)2(H2O)4].4H2O(phen=邻菲啰啉;BTC=均苯三甲酸),采用X射线单晶衍射结构分析及元素分析、红外光谱等表征,并用TGA检测了该配合物的热稳定性.晶体属于三斜晶系,空间群为P-1,晶胞参数a=0.84038(7)nm,b=0.92048(8)nm,c=1.64793(14)nm,α=97.3850(10)°,β=102.7930(10)°,γ=104.9700(10)°,V=1.17736(17)nm3,F(000)=622,Z=1.标题化合物的不对称结构是由NiO6单元和1个二聚物Ni2N4O12单元组成的,该二聚物单元通过2个邻菲啰啉和2个均苯三甲酸分子构筑了1个八元环.氢键将2个独立的结构单元连接成三维结构.
The complex [Ni(H2O)6]·[Ni2(phen)2(BTC)2(H2O)4]·4H2O(H3BTC benzene-1,3,5-tricarboxylic acid,phen =1,10-phenanthroline)was synthesized from the hydrothermal reaction and characterized by single crystal X-ray diffraction analysis,element analysis and infrared spectrum.The result shows that the crystal structure belongs to Triclinic system,space grou P-1 with a=0.840 38(7)nm,b= 0.920 48(8)nm,c=1.647 93(14)nm,α=97.385 0(10)°,β=102.793 0(10)°,γ=104.970 0(10)°,V=1.177 36(17)nm3,F(000)=622,Z=1.The asymmetrical structure of the polymer consists of NiO6 unit and a dimeric Ni2N4O12unit,and a eight-membered ring is constructed through two phen and two BTC ligands.The two isolated structure are linked further by hydrogen bonds(O—H···O)to form three dimensional supremolecular structure.
