Article abstract of DOI:10.1039/DT9850001523

The complexes cis- (A) and trans- (B) have been prepared by reduction of WCl6 or with Mg in tetrahydrofuran (thf) under N2 in the presence of the appropriate phosphine.Dinitrogen is displaced from (A) by CO to give cis-.Compound (B) reacts with I2, FeCl3, and CuCl2 to give Y (Y = I3, FeCl4, or CuCl2) and with HCl to give the cation ⁺.Both complexes (A) and (B) undergo reversible one-electron oxidation in thf.The complex trans- gives trans- (R = Me or Et) on treatment with RCN.X-ray analysis of the related comlex, cis-, shows a well defined octahedral structure in which the dinitrogen ligands have different environments and the W-N distances are 1.983(3) and 2.015(3) Angstroem.
