Abstract

In the title complex, [Ni(NO3)2(C14H16N6O2)]·H2O, the NiII atom, lying on a twofold rotation axis, is coordinated by a tetradentate 3,3′-{(1E,1′E)-1,1′-[ethane-1,2-diylbis(azan-1-yl-1-ylidene)]bis(ethan-1-yl-1-ylidene)}dipyrazine 1-oxide ligand and two mutually trans monodentate nitrate anions in a distorted octahedral geometry. The lattice water molecule is located on a twofold rotation axis. The complex molecules are linked by the water molecules 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.
