title: Bis[2-(2-amino-ethyl)-1H-benzimidazole-κN,N]zinc(II) bis-(perchlorate).
abstract: In the title compound, [Zn(C(9)H(11)N(3))(2)](ClO(4))(2), the Zn(II) 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 tetra-hedral geometry. The crystal packing is dominated by N-H⋯O inter-actions involving the perchlorate anions and π-π stacking inter-actions with an inter-planar separation of 3.42 Å. A weak C-H⋯O inter-action is also present.
