摘要

Two dianionic amine bis(thiolato) ligands are introduced and their reactions with titanium tetra(iso-propoxide) studied; ligand N₂H₂S₂H₂ (1) having NH donor groups leads exclusively to dinuclear [{Ti(N₂H₂S₂)(OⁱPr)}₂] (2) along with an oxidation product of the ligand (3) whereas ligand N₂Me₂S₂H₂ (4) having an additional N-substituent leads exclusively to a mononuclear [Ti(N₂Me₂S₂)(OⁱPr)₂)] (5) type complex.
