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.
