%X In the title compound, [Ni(NO3)(C13H20N4)2]NO3, the NiII ion shows a distorted octahedral geometry formed by four N atoms from two bis(2-ethyl-5-methyl-1H-imidazol-4-yl)methane ligands and two O atoms from a chelating nitrate anion. Three ethyl groups in the complex cation and the O atoms of the uncoordinated nitrate anion are disordered over two sets of positions [occupancy ratios of 0.52 (3):0.48 (3) and 0.63 (3):0.37 (3), respectively]. In the crystal, intermolecular N¡ªH...O hydrogen bonds connect the complex cations into a zigzag chain along [010] and further N¡ªH...O hydrogen bonds between the chains and the uncoordinated nitrate anions lead to layers parallel to (100).
