【 摘 要 】

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 N2-[(benzo[h]quinolin-2-yl)meth­yl]-N2′-[(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.
