Abstract

original image

Three new chromium complexes containing the rare ligand combination CS/NO have been synthesized with the aim of comparing the acceptor strength of diatomic lignands CO, CS, and NO. It can be deduced from the spectra that CS in (1) is a more effective acceptor than CO in CpCr(CO)2(NO). In the cation (3), however, CS is a weaker acceptor than CO in [CpCr(CO)(NO)2]+. These observations are in accord with rules proposed by Andrews.
