In the title compound, [Co(NO(3))(C(9)H(11)N(3))(2)]Cl·3H(2)O, the Co(II) atom is coordinated by four N atoms from two chelating 2-(2-amino-eth-yl)-1H-benzimidazole ligands and two O atoms from one nitrate anion in a distorted octa-hedral 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 mol-ecules into a three-dimensional network. π-π inter-actions 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].
在标题化合物[Co(NO₃)(C₉H₁₁N₃)₂]Cl·3H₂O中，Co(II)原子由来自两个螯合的2-(2-氨基乙基)-1H-苯并咪唑配体的四个N原子和来自一个硝酸根阴离子的两个O原子在扭曲的八面体配位环境中配位。在晶体中，N-H⋯Cl、N-H⋯O、O-H⋯Cl和O-H⋯O氢键将络合阳离子、氯离子阴离子和溶剂水分子连接成三维网络。观察到咪唑环与苯环之间以及苯环之间的π-π相互作用[质心-质心距离 = 3.903 (3)、3.720 (3)、3.774 (3)和3.926 (3) Å]。
