A new nickel coordination compound [Ni(L2-)(2,2′-bipy)(H2O)]·2H2O (H2L=phenyliminodiacetic acid) was obtained by self-assembly of phenyliminodiacetic acid, 2,2′-bipy, and NiCl2·6H2O in the mixed solvent of...A new nickel coordination compound [Ni(L2-)(2,2′-bipy)(H2O)]·2H2O (H2L=phenyliminodiacetic acid) was obtained by self-assembly of phenyliminodiacetic acid, 2,2′-bipy, and NiCl2·6H2O in the mixed solvent of water and ethanol (V∶V=1∶1). The complex was characterized by elemental analysis, IR spectra, and X-ray crystallography analysis. The crystal is monoclinic, space group P21 / c with a=0.867 4(2) nm, b=0.907 3(1) nm, c=2.643 5(5) nm, β=91.01(1)°, V=2.080 2(4) nm3, Z=4, F(000)=992, Dc=1.520 Mg·m-3, R1=0.027 0 and wR2=0.067 5. In the complex, nickel atom is coordinated with a distorted octahedral geometry and extensive hydrogen bonds link the complexes into a 2D network structure. CCDC: 244926.展开更多

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.展开更多
