The new complexes (RN=CH-CH=NR)Co(NO)(CO), R = isopropyl (1), 2,6-diisopropylphenyl (2) and p-tolyl (3), were synthesized and spectroscopically characterized. Compounds I and 2 could be crystallized for X-ray structure analysis, CO/NO disorder was observed for 1. The results indicate a negligible amount of charge transfer from the Co(NO)(CO) moiety to the 1,4-diaza-butadiene acceptor ligands in the ground state, in agreement with DFT calculations on I and as similarly reported for related 1,4-diaza-1,3-butadiene complexes of Ni(CO)(2) and Fe(NO)(2).
