Abstract

The complex [Ti(NC4Me4)(NMe2)3] has been synthesized, characterized by mass spectrometry, 1H and 13C NMR and theoretically studied by ab initio molecular orbital calculations. The N-σ-coordination mode of the heterocyclic ring was predicted by the 13C NMR data and confirmed by the optimized geometry of the model complex [Ti(NC4H4)(NMe2)3]. The different bonding modes of the 2,3,4,5-tetramethylpyrrolyl ligand are discussed.
