(3,3'-{(1E,1'E)-1,1'-[Ethane-1,2-diylbis(azan-1-yl-1-yl­idene-[kappa]N)]bis­(ethan-1-yl-1-yl­idene)}di­pyrazine 1-oxide-[kappa]N4)bis­(nitrato-[kappa]O)nickel(II) monohydrate

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.
