Putting Chromium on the Map for N2 Reduction: Production of Hydrazine and Ammonia. A Study of cis-M(N2)2 (M = Cr, Mo, W) Bis(diphosphine) Complexes

Abstract

The first complete series of isostructural Group 6 bis(dinitrogen) complexes of the formula cis-[M(N2)2(PEtNRPEt)2] (M = Cr, Mo, W; R = 2,6-difluorobenzyl) have been structurally and spectroscopically characterized. Protonolysis experiments reveal that only Cr affords N2H5+ and NH4+ from the reduction of the N2 ligands. Acknowledgment.
