English abstract:
DFT calculations were carried out on Ti2(OCH3)8 (NH2CH3)2 and Ti2(OCH3)8(NH3)2, which are model compounds for the previously isolated amine adducts Ti2(OR)8(NH2 R′)2. The calculations show that the Ti-N bond strength is weak; however, coordination of the amine to the metal center is supported by a N-H...O hydrogen bond of the amine with the neighboring alkoxo ligand. The Ti-N interaction is purely σ in nature, while the Ti-O interactions include both σ and π contributions. The lowest unoccupied molecular orbitals are mainly localized on Ti t2g-like orbitals.
