Application

Used to form mixed chloro-aryloxide compounds, such as [Ta(OC6H3-2,6-i-Pr2)2Cl3]2, which form pyridine or phosphine adducts with a distortedsix-coordinate geometry. Also used as a starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18, for which electron and stability studies were performed.
