Abstract
The title compound, [ZnBr2(C11H13N3)], was synthesized by hydrothermal reaction of ZnBr2 and (S)-2-(pyrrolidin-2-yl)-1H-benzimidazole. The ZnII atom has a distorted tetrahedral geometry and is coordinated by two N atoms from the chelating organic ligand and two terminal Br− anions. In the crystal structure, molecules are linked into a chain along the [101] direction by N—H⋯Br and C—H⋯Br hydrogen bonds.

Metal-organic coordination compounds provide a class of complexes displaying interesting chemical and physical properties such as fluorescence and dielectric behaviors (Aminabhavi et al, 1986; Ye et al, 2008; Fu et al, 2007)
The homochiral ligand S-2-(pyrrolidin-2-yl)-1H-benzimidazole was synthesized by reaction of S-pyrrolidine-2-carboxylic acid and benzene-1,2-diamine according to the procedure described in the literature (Aminabhavi et al, 1986)
