The phosphiniminato-substituted tungsten(VI) fluorides (PhpMe3)P=NWF5 (2), 2WF4 (3), (Me3P=N)2WF4 (4) and 2WF4 (6) have been prepared from the corresponding SiMe3 derivatives by reaction with WF6.The starting materials (PhpMe3)P=NSiMe3 (1) and (t-buNH)Ph2P=NSiMe3 (5) are obtained by the reaction of the phosphanes with Me3SiN3.The crystal structure of 4 shows that the cis isomer was formed.Although the molecular geometry of 4 is similar to that of (Ph3P=N)2WF4, some important differences are observed arising from the different electronic prop erties of the substituents. - Key words: X-Ray, Tungsten, Fluorine, Kinetic Stability
