Synthesis and structure of a perpendicular bridging alkylidyneamine ligand in [W2(η-C5H4Pri)2Cl4(µ-Cl)(µ-EtCNH)]
Abstract
Treatment of the WW triply-bonded dimers [W2(η-C5H4R)2Cl4](R = Pri or Me) with R′CN (R′= Me, Et, or Ph) followed by HCl gas affords the complexes [W2(η-C5H4R)2Cl4(µ-Cl)(µ-R′CNH)] in quantitative yield; the X-ray crystal structure for R = Pri, R′= Et reveals a perpendicular bridging EtCNH ligand.
