摘要
A novel dinuclear complex of Ni2(p-PhDTA)(2,2′-bipy)2(H2O)2 ·4H2O (p-PhDTA2-=para-phenylenediamine-N,N,N′,N′-tetraacetate)has been synthesized. The complex was characterized by elemental analysis, IR spectra, thermo-analysis and X-ray diffraction. The crystal belongs to triclinic, space group P1 with a=0.976 3(7)nm, b=0.989 41(7) nm, c=1.084 29(8) nm, ?琢=65.661 0(10)°, ?茁=75.234 0(10)°, ?酌=85.616 0(10)°, Z=2, V=0.925 44(12) nm3, Dc=1.568 g·cm-3, R1=0.031 5, wR2=0.081 4. In the complex, the central Ni?髤 ion is coordinated in a distorted octahedral geometry, defined by two carboxyl O atoms and one N atom from same p-PhDTA2-group, two N atoms from 2,2′-bipyridine ligand and one water molecule. The two nickel ?髤 ions are linked by p-PhDTA2-group into a dinuclear structure and extensive hydrogen bonds link the complex into a 2D supramolecular network. CCDC: 294084.
A novel dinuclear complex of [Ni2（p-PhDTA） （2,2＇-bipy）2（H2O）2]-4H2O （p-PhDTA2-=para-phenylenediamine-N,N,N＇,N＇-tetraacetate）has been synthesized. The complex was characterized by elemental analysis, IR spectra, thermo-analysis and X-ray diffraction. The crystal belongs to triclinic, space group P1^- with a=0.976 3 （7）nm, b = 0.989 41（7） nm, c=1.084 29（8） nm, α=65.661 0（10）°,β=75.234 0（10）°, γ=85.616 0（10）°, Z=2, V=0.925 44（12） nm^3, Dc=1.568g·cm^-3, R1=0.031 5, wR2=0.081 4. In the complex, the central Ni（Ⅱ） ion is coordinated in a distorted oc- tahedral geometry, defined by two carboxyl O atoms and one N atom from same p-PhDTA^2- group, two N atoms from 2,2＇-bipyridine ligand and one water molecule. The two nickel （Ⅱ） ions are linked by p-PhDTA^2- group into a dinuclear structure and extensive hydrogen bonds link the complex into a 2D supramolecular network. CCDC： 294084.
