Application
Employed in the synthesis of metal-rich layered tellurides, TaNi2Te2 and TaCo2Te2, which possess ideal characteristics for photovoltaic applications, for surface scanning studies, and which may give clean and atomically flat surfaces. Starting material for new edge-bridged octahedral M6 cluster compounds such as CsErTa6Cl18, for which electron and stability studies were performed.
