(2,2'-Bipyridine-?(2) N,N')[bis-(diphenyl-thio-phosphino-yl)meth-yl]lithium(I) benzene monosolvate.

ABSTRACT: In the title benzene-solvated heteroleptic lithium complex, [Li(C25H21P2S2)(C10H8N2)]·C6H6, the Li(I) ion is four-coordinated in a distorted tetra-hedral geometry by two S atoms and two N atoms of the two chelating ligands, viz. bis-(diphenyl-thio-phosphino-yl)methyl and 2,2'-bipyridine. The 2,2'-bipyridine mol-ecule is slightly twisted with a dihedral angle between the pyridine rings of 7.35?(12)°. Intra-molecular C-H?S hydrogen bonds are present. In the crystal, mol-ecules are stacked along the c axis by ?-? inter-actions, with centroid-centroid distances of 3.6021?(15) and 3.6401?(16)?Å. The crystal structure also features weak C-H?? inter-actions.
