1,8-Diazabicyclo[5.4.0]undec-7-en-8-ium bromido(phthalocyaninato)zincate

Abstract

The title compound, (C9H17N2)[ZnBr(C32H16N8)], contains a bromido­(phthalocyaninato)zincate anion and a protonated 1,8-di­aza­bicyclo­[5.4.0]undece-7-ene cation, [DBUH]+. The central ZnII atom has a distorted square-pyramidal geometry, with four iso­indole N atoms of the macrocycle in equatorial positions and a bromide ion in the axial position. The latter has a relatively high displacement parameter, but no evidence for disorder was obtained. The central ZnII atom is displaced by 0.488 (3) Å from the mean plane defined by the four iso­indole N atoms. The [DBUH]+ cation is involved in an almost linear N—H⋯Br hydrogen bond. In the crystal, π–π inter­actions lead to a relatively short distance of 3.366 (3) Å between the phthalocyaninate rings.
