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.
在标题化合物[Ni(C₇H₃NO₄)(C₁₂H₉N₅)(H₂O)₂]中,Ni(II)原子由吡啶 - 2,6 - 二羧酸酯配体的一个N原子和两个O原子、赤道位置的3,5 - 双(4 - 吡啶基)-1H - 1,2,4 - 三唑配体的一个N原子以及轴向位置的两个水分子以扭曲的八面体几何构型配位。晶体堆积通过分子间的O - H⋯O、O - H⋯N和N - H⋯O氢键得以巩固。
