  摘要：

  3-Hydroxyflavone and bipyridyl ligands coordinate to the Ni-II centre in an octahedral arrangement, giving the title complex, [Ni(C15H9O3)(2)(C5H5N)(2)]. Since the Ni atom lies on a centre of symmetry, all the trans O-Ni-O and N-Ni-N bond angles are 180 degrees; those of O-Ni-N are close to 90 degrees. The Ni-O(carbonyl), Ni-O(hydroxy) and Ni-N distances are 2.067(2), 2.023(2) and 2.180(2) Angstrom, respectively. All the C-C bond distances are normal with values between 1.366 (3) and 1.406(4) Angstrom, except those which are close to the coordinated C-O bonds: C(1)-C(2), C(2)-C(3) and C(9)-C(10) are 1.457(4), 1.445(3) and 1.462(4) Angstrom, respectively. All rings are almost planar, except those involving coordinated O atoms. The dihedral angles between the flavonato planes and the pyridyl ligands are quite large with values of ca 84 degrees. The angles between the planes in the hydroxyflavone ligand are less than 10 degrees.
