| Abstract: A complex of nickel(Ⅱ) with pyrazine-2,3,5,6-tetracarboxylic acid and 2,2'-bipyridine,[Ni(ptcH2) (bpy) (H2O)],was synthesized by hydrothermal reaction of Ni(NO3)2·6H2O with pyrazine-2,3,5,6-tetracarboxylic acid and 2,2'-bipyridine at 160℃and characterized by elemental analysis,IR and X-ray diffraction single crystal structure determined.The crystal belongs toMonoclinic system,with space group P21/c,a=1.3279(7) nm,b=1.2797(7) nm,c=1.1614(7) nm;β=113.435(8) °,V=1.8106(17) nm3,Z=4.The coordination environment of nickel(Ⅱ) ion is a distorted octahedral geometry.The title complex is a mononuclear structure which is assembled into 3D supramolecular architecture bystronghydrogen bonds.CCDC:661507. |
