The infrared spectra of products of tantalum and ruthenium reactions with fluorine isolated in solid argon

Abstract

The IR spectra of the products formed when molecular fluorine was passed over tantalum and ruthenium heated to 100-1100 degreesC and isolated in inert matrices at 12 K were studied. In the Ta + F-2 system, bands of (TaF5)(3), TaF5, and TaF4 were observed. In the Ru + F-2 system, the major reaction product was monomeric ruthenium pentafluoride. The structures of metal fluorides of various compositions are discussed
