title: Clemizoledichlorocobalt(II).
abstract: The structure of dichloro[1-(p-chlorobenzyl)-2-(1-pyrrolidinylmethyl-N)-1, 3-benzimidazole-N(3)]cobalt(II), [CoCl(2)(C(19)H(20)ClN(3))], 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) A, respectively. The geometry around cobalt is distorted tetrahedral, with significantly different Co-Cl distances of 2.217 (2) and 2.233 (2) A, and the pyrrolidinyl ring is disordered.
