Titanocene(III) pseudohalides: an ESR and structural study
Original language description
A series of complexes of the type [Ti('Cp)(2)Y] {'Cp = eta(5)-C5H5 (Cp), eta(5)-C5H4SiMe3 (SiCp), eta(5)-1,3-C5H3(Me3Si)(2) (Si2Cp); Y = Cl-, CN-, NCS-, NCSe-, dicyanamide (dca), tricyanomethanide (tcm) and 1,2,3,4-thiatriazol-5-thiolate (ttt)) were prepared and studied by ESR spectroscopy. Ring-substituted compounds [Ti(SiCp)(2)Cl], [Ti(Si2Cp)(2)Cl], [Ti(SiCp)(2)CN] and [Ti(Si2Cp)(2)CN] dissolved in coordinating solvents exist in an equilibrium with solvated species. The thiatriazolthiolate ligand in complexes [Ti('Cp)(2)(ttt) behaves as a S,N-chelator to yield a thermally unstable 4-membered chelate ring having the ESR signal with significant splitting due to coupling with one 14N nucleus. Solutions of [Ti('Cp)(2)Y] = NCS-, NCSe-, dca and tcm) readily dissolve the additional pseudohalide salt giving anionic species [Ti('Cp)2Y2]- with a characteristic ESR pattern caused by superhyperfine splitting by two 14N nuclei. Cyanide complexes dissolve additional KCN as well, but no coupling to
