WebThe transition metal bis-dithiolene complexes (MS4C4X4) can be used as acceptor molecules in π-donor-acceptor-type compounds, or as radical anions in mixed valence compounds. These compounds are in the wide middle ground between the strictly organic or inorganic molecular solids on which extensive research has led to the discovery of … WebThe driving force for ligand bending should be lower in systems having more or fewer electrons (e.g. Re(S2C2Ph2)3 or V(S2C2Ph2)3, respectively). While the steric bulk of the dithiolate ligands in the latter complexes may also influence the degree of ligand bending, this is probably a secondary effect.
WebThus, X-ray studies of Re(S2C2Ph2)3 and V(S2C2Ph2)3 showed trigonal prismatic geometry. However, Gray and co-workers have concluded from electronic spectral measurements that Ti(nrnt) (mnt = maleonitriledithiolate) has a severely distorted octahedral structure.
