The zinc(II) atom in the title compound, [Zn(C48H31N4)(CF3SO3)](CF3SO3)·1.5CH2Cl2, adopts a distorted five-coordinate square-pyramidal geometry. It is coordinated by one trifluoromethanesulfonate ligand and four N atoms of the N 2-[(benzo[h]quinolin-2-yl)methyl]-N 2′-[(benzo[h]quinolin-2-yl)methylidene]-1,1′-binaphthyl-2,2′-diamine ligand. The complex is present as a single-stranded P-helimer monohelical structure incorporating π-π and/or σ-π interactions. One of the imine bonds present in the original ligand framework is reduced, leading to variations in bond lengths and torsion angles for each side of the ligand motif. The imine-bond reduction also affects the bond lengths involving the metal atom with the N-donor atoms located on the imine bond. There are two molecules of the complex in the asymmetric unit. One of the molecules exhibits positional disorder within the coordinating trifluoromethanesulfonate ion making the molecules symmetrically non-equivalent.
