Abstract: | The structure of dichloro1‐(p‐chlorobenzyl)‐2‐(1‐pyrrolidinylmethyl‐N)‐1,3‐benzimidazole‐N3]cobalt(II), CoCl2(C19H20ClN3)], contains a molecule of clemizole bound in a bidentate manner to cobalt through its imidazole and pyrrolidinyl N atoms, with significantly different Co—N distances of 1.976 (5) and 2.126 (5) Å, respectively. The geometry around cobalt is distorted tetrahedral, with significantly different Co—Cl distances of 2.217 (2) and 2.233 (2) Å, and the pyrrolidinyl ring is disordered. |
