Previously we have shown that 14N and 95Mo NMR are useful techniques for studying piano stool nitrosyl complexes such as (η5-C5H5)Mo(CO)2NO.1 Recently a number of related nitrosyl and thionitrosyl complexes of group 6 metals have been synthesized.2,3 The availability of new thionitrosyl complexes of the Cr, Mo, W triad has permitted us to directly compare the spectroscopic properties of several pairs of metal nitrosyl/thionitrosyl species. Here we present the first nitrogen NMR data for a thionitrosyl complex, and we demonstrate the applicability of 14N NMR, particularly in combination with 95Mo NMR and 13C NMR, for providing specific experimental information on the relative electron distribution and bonding of nitrosyls and thionitrosyls with metals.
