چکیده
In the title compound, [Ni(C(7)H(3)NO(4))(C(12)H(9)N(5))(H(2)O)(2)], the Ni(II) atom is coordinated in a distorted octa-hedral geometry by one N and two O atoms from a pyridine-2,6-dicarboxyl-ate ligand, one N atom from a 3,5-bis-(4-pyrid-yl)-1H-1,2,4-triazole ligand in equatorial positions and two water mol-ecules in axial positions. The crystal packing is consolidated by inter-molecular O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds.
