Zusammenfassung
(RN:CHCH:NR)Co(NO)(CO), R = iso-Pr (1), 2,6-diisopropylphenyl (2) and p-tolyl (3), were synthesized and spectroscopically characterized. Compds. 1 and 2 could be crystd. for x-ray structure anal., CO/NO disorder was obsd. for 1. The results indicate a negligible amt. of charge transfer from the Co(NO)(CO) moiety to the 1,4-diazabutadiene acceptor ligands in the ground state, in agreement with DFT calcns. on 1 and as similarly reported for related 1,4-diaza-1,3-butadiene complexes of Ni(CO)2 and Fe(NO)2.
