Abstract

In the title compound, [Zn(C9H11N3)2](ClO4)2, the ZnII atom resides on a crystallographic twofold axis and is coordinated by two benzimidazole N [Zn⋯N = 1.993 (4) Å] and two amine N atoms [Zn⋯N = 2.036 (4) Å] in a distorted tetra­hedral geometry. The crystal packing is dominated by N—H⋯O inter­actions involving the perchlorate anions and π–π stacking inter­actions with an inter­planar separation of 3.42 Å. A weak C—H⋯O inter­action is also present
