A planar W 3 N 3 ring showing marked alternation in the bond lengths (structures shown on the right) is the distinctive structural element in the trimeric tungsten nitride 1 (R = C(CH 3 ) 2 CF 3 ), which was obtained by reaction of the alkoxide [W 2 (OR) 6 ] with benzonitrile. When R = Si t BuMe 2 , a complex is formed in solution with a central W 2 O 2 ring and terminal nitrio ligands.\documentclass{article}\usepackage{amssymb}\pagestyle{empty}\begin{document}$$[\{{\rm NW(OR)}_3\}_3]\quad{\bf 1}$$\end{document}
