Bis[2-(2-amino­eth­yl)-1 H-benzimidazole-κ ² N ², N ³](nitrato-κ ² O, O′)cobalt(II) chloride trihydrate

Abstract

In the title compound, [Co(NO ₃)(C ₉H ₁₁N ₃) ₂]Cl·3H ₂O, the Co ^II atom is coordinated by four N atoms from two chelating 2-(2-amino­eth­yl)-1 H-benzimidazole ligands and two O atoms from one nitrate anion in a distorted octa­hedral coordination environment. In the crystal, N—H⋯Cl, N—H⋯O, O—H⋯Cl and O—H⋯O hydrogen bonds link the complex cations, chloride anions and solvent water mol­ecules into a three-dimensional network. π–π inter­actions between the imidazole and benzene rings and between the benzene rings are observed [centroid–centroid distances = 3.903 (3), 3.720 (3), 3.774 (3) and 3.926 (3) Å].
