Description

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 distorted six-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.
