【 摘 要 】

We report herein the synthesis, crystallographic analysis and a study of the non-covalent inter­actions observed in the new 4′-substituted terpyridine-based derivative bis­[4′-(isoquinolin-2-ium-4-yl)-4,2′:6′,4′′-terpyridine-1,1′′-diium] tris-[tetra­chlorido­zincate(II)], (C24H19N4)2[ZnCl4]3 or (44TPH3)2[ZnCl4]3, where (44TPH3)3+ is the triply protonated cation 4′-(isoquinolinium-4-yl)-4,2′:6′,4′′ terpyridinium. The compound is similar in its formulation to the recently reported 2,2′:6′,2′′ terpyridinium analogue {bis­[4′-(isoquinolin-2-ium-4-yl)-2,2′:6′,2′′-terpyridine-1,1′′-diium] tris­[tetra­chlorido­zincate(II)] monohydrate; Granifo et al. (2017). Acta Cryst. C73, 1121–1130}, although rather different and much simpler in its structural features, mainly in the number and type of non-covalent inter­actions present, as well as in the supra­molecular structure they define.
