The binary fluorides of ruthenium were selected for several reasons. Greater structural precision fromX-ray diffraction data was more likely than from a third transition series set of fluorides. Four binary fluorides (a hexa-, penta-, ° tetra-," and trifluo-ride ) of ruthenium were known to be preparable, and the structure of the tetrafluoride was of special interest.

Ruthenium(VI) oxide tetrafluoride, [RUOF4], is reported to have been prepared by the action of a mixture of BrFj and Br2 on ruthenium. The enthalpy and entropy of vaporization. X-ray powder pattern and magnetic properties (jt = 2.91 BM at room temperature) have been measured. However more recently other workers also claim to have prepared [RUOF4] (by the fluorination of RuOj at 400-500°C), but it shows different properties to the earlier product. Evidence for its formulation is based on mass spectroscopy (which shows the molecular ion [RUOF4 ] ), elemental analysis and IR spectrum (v(Ru=0)= 1040cm ). The solid is unstable, even at room temperature, decomposing to [RUF4] and A report on the physical and chemical properties of...
