In the title complex, [CuCl(C8H8N2OS)(C18H15P)2]·2CH3OH, the CuI ion is coordinated by one chloride anion, one S atom from the 5-methoxy-1H-benzimidazole-2(3H)-thione ligand and two P atoms from two triphenylphosphine ligands in a distorted tetrahedral geometry. One of the N-bound H atoms is involved in an intramolecular N—HCl hydrogen bond, while another one interacts with the solvent methanol molecule via an N—HO hydrogen bond. Intermolecular O—HCl and O—HO hydrogen bonds link two further complex molecules and four solvent molecules into a centrosymmetric structural unit. The short distance of 3.624 (4) Å between the centroids of the five- and the six-membered rings of two benzimidazole fragments indicates the presence of π–π interactions.
