A strong π acceptor and a strong π donor —NO and O ligands, respectively—coordinated cis to the same metal atom are present in the complex 1 . The NO stretching frequency of the linear WNO unit occurs at extremely low wavenumber (1433 cm −1 ). The red complex 1 forms by reduction of [WL(CO) 2 (NO)] + to [WL(NO)(CO)(Me)] (L = heterocycle) followed by reaction with O 2 .
