在溶剂热条件下,利用硝酸镍、邻二氮菲和邻苯二甲酸反应,合成了一种新的三维超分子化合物[Ni(C12H8N2)(C8H4O4)(H2O)].H2O,对其进行了元素分析、差热-热重分析、红外光谱表征和X射线单晶衍射测定.晶体属正交晶系,Pbcm空间群,a=1.1648(2)nm,b=1.1162(3)nm,c=1.4059(6)nm;Z=4,V=1.8250(8)nm3,Mr=439.10,F(000)=908,Dc=1.5982 mg/m3,μ(MoKα)=1.108 mm-1,R1=0.0298,WR2=0.0749.Ni原子为五配位,呈畸变四方锥构型,通过邻苯二甲酸根的桥联作用形成了一维螺旋链状结构,相邻链之间依靠氢键和芳环堆积作用形成三维的超分子网络.
A new three-dimensional supramolecular compound [Ni (C12H8N2) (C8H4O4) (H2O)]. H2O was synthesized by the reaction of nickel nitrate, phenanthroline and phthalic acid under solvothermal conditions Elemental analysis, DTA-TG, FT-IR and single crystal X-ray diffraction.The crystal belongs to orthorhombic system with Pb = 1.1648 (2) nm and b = 1.1162 (3) nm, c = 1.4059 (6) nm; Z = 4, V = 1.8250 (8) nm3, Mr = 439.10, F000 = 908, Dc = 1.5982 mg / WR2 = 0.0749.Ni atoms are pentacoordinated and show a distorted tetragon pyramidal structure, forming a one-dimensional helical chain structure through the bridging effect of phthalates, and the adjacent chains rely on hydrogen bonding and aromatic ring stacking Forming a three-dimensional supramolecular network.
