In the title complex, [Ni(NO3)2(C14H16N6O2)]·H2O, the Ni(II) atom, lying on a twofold rotation axis, is coordinated by a tetra-dentate 3,3'-{(1E,1'E)-1,1'-[ethane-1,2-diylbis(azan-1-yl-1-yl-idene)]bis-(ethan-1-yl-1-yl-idene)}di-pyrazine 1-oxide ligand and two mutually trans monodentate nitrate anions in a distorted o-cta-hedral geometry. The lattice water mol-ecule is located on a twofold rotation axis. The complex mol-ecules are linked by the water mol-ecules through O-H⋯O hydrogen bonds into a chain along [001]. Further C-H⋯O hydrogen bonds lead to the formation of a three-dimensional network.
在标题配合物[Ni(NO₃)₂(C₁₄H₁₆N₆O₂)]·H₂O中，位于二重旋转轴上的Ni(II)原子由一个四齿的3,3'-{(1E,1'E)-1,1'-[乙烷-1,2-二基双(氮杂-1-基-1-基亚甲基)]双-(乙烷-1-基-1-基亚甲基)}二吡嗪1-氧化物配体和两个相互反位的单齿硝酸根阴离子以扭曲的八面体几何构型配位。晶格水分子位于二重旋转轴上。配合物分子通过水分子以O-H⋯O氢键沿[001]方向连接成链。进一步的C-H⋯O氢键导致形成三维网络。
