C27H26Cl1.5N6.5NiO2.5S crystallizes in the polar space group Fdd2 with 16 formulas per unit cell. The crystal structure is formed by cations of [Ni(phen)2(thiourea)Cl]+, chloride and nitrate counter ions and ethanol solvate molecules. The nickel atom is octahedrically coordinated to two bidentate phen, a monodentate thiourea and to a chlorine ion. Both the chloride and nitrate anions, which provide to the charge balance, are placed at special positions in a two fold symmetry axis. Hydrogen bonds play a key role in packing and conformation of the cation, determining a three-dimentional network.
