Tantalum(V) chloride, Puratronic™, 99.99% (metals basis)

Description

CAS: 7721-01-9 | Cl5Ta | 358.20 g/mol

Tantalum(V) chloride is 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. It is also used as a starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18.
