The reactions of tungsten hexafluoride with ethylene glycol, 1,2- and 1,3-propanediol, and 2,3-butanediol have been studied by /sup 19/F NMR. As a result, dimeric, trimeric, and tetrameric compounds with four or five fluoride atoms in which the tungsten atoms are joined to one another by deprotonated moieties of the diols, and each metal atom is bonded to the other metal atoms by means of only one such group, were obtained. Dimeric compounds, in which the two tungsten atoms are joined by two bridging deprotonated moieties of the diols in a stabilized gauche conformation, are obtained at an appropriate concentration of the diols. When the diol:WF/sub 6/ ratio is increased, monomeric octahedral compounds of tungsten with three fluorine atoms form. The parameters of the /sup 19/F NMR spectra of the compounds obtained have been determined.
