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 .
