Tungsten(V) oxytrichloride and oxytribromide. Part II. Reactions with donor molecules and the related behaviour of molybdenum(V) oxytribromide

Abstract

The oxytrihalides MoOBr3, WOCl3, and WOBr3 react with a variety of oxygen and nitrogen donor molecules to form compounds of empirical formula MOX3,2L which are formulated as monomers containing terminal Mo[double bond, length half m-dash]O or W[double bond, length half m-dash]O groups. The compounds have been characterised by oxidation-state titrations, infrared and electronic spectral measurements, and temperature range (320–80°k;) magnetic studies. The direct reaction of WOCl3 with pyridine or trimethylamine give the dark blue 1 : 1 adducts WOCl3,py or WOCl3,NMe3, respectively, whose magnetic properties are very similar to those of WOCl3 itself, and which are believed to be octahedral polymers with W–O–W bridges.
