ChemInform Abstract: Gas-Phase Electron Diffraction Study of Ruthenium(V) Fluoride and Osmium(V) Fluoride.

Abstract

The molecular structures of the constituents of gaseous ruthenium(V) fluoride and osmium(V) fluoride at approximately 120 o C have been determined by electron diffraction. At this temperature, for both RuF 5 and OsF 5 , the main constituents are trimeric molecules together with smaller amounts of dimeric species. The trimeric molecules contain three six-coordinate metal atoms each of which are bonded to four terminal fluorine atoms and to two further ring fluorine atoms in a bridging manner
