energy for the flip around the S-S axis was determined for 13 to be 69 kJ/mol. The bis(dithiolate) ligand 1,4-bis[(2,3-dimercaptobenzamido)methyl]benzene (H(4)-4) was prepared from 2,3-dimercaptobenzoic acid and converted into the dinuclear air-stable titanocene complex [(eta(5)-C(5)H(5))(2)Ti}(2)(4)] (19). Complex 19 reacts with HCl/CHCl(3) with liberation of free H(4)-4 while reaction with NMe(4)Cl
