It was the purpose of this study to investigate the reaction of molybdenum and tungsten dioxides with carbon tetrachloride and bromoform (via the method of Knox and Tyree) to produce anhydrous molybdenum and tungsten tetrachlorides and bromides and to determine whether the method is a reliable one for the synthesis of these compounds. Out of this grew an investigation into the preparation of the oxochlorides of tungsten(VI) using the same preparative technique.
The results of this study are here set forth. An attempt is made to systematize the published material on the synthesis and properties of the binary halides of molybdenum(IV) and tungsten(IV) and the oxochlorides of tungsten(VI). Extensive calculations have been carried out by A. Glassner in 1957 and L. Brewer and co-workers in 1950 on the estimation of thermochemical and thermodynamic data for the tetrahalides of molybdenum and tungsten. These data are in general based on analogy with compounds of neighboring elements in the Periodic Table. Even though these values are subject to uncertainty, they are included here for comparative purposes.
