| 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. |
| Packaging: | 5, 25 g in poly bottle |
| Preparation Note: | Used in the preparation of a simple catalyst for the polycyclotrimerizations of alkenediynes. Used for the plasma-enhanced atomic layer deposition of tantalum nitride films. |
