In the title benzene-solvated heteroleptic lithium complex, [Li(C25H21P2S2)(C10H8N2)]·C6H6, the LiI ion is four-coordinated in a distorted tetrahedral geometry by two S atoms and two N atoms of the two chelating ligands, viz. bis(diphenylthiophosphinoyl)methyl and 2,2′-bipyridine. The 2,2′-bipyridine molecule is slightly twisted with a dihedral angle between the pyridine rings of 7.35 (12)°. Intramolecular C—HS hydrogen bonds are present. In the crystal, molecules are stacked along the c axis by π–π interactions, with centroid–centroid distances of 3.6021 (15) and 3.6401 (16) Å. The crystal structure also features weak C—Hπ interactions.
