Phosphine/thiolate-containing dinitrosyl cobalt complexes (DNCCs): synthesis, characterization, interconversion, X-ray diffraction identification and NO release.

Cobalt carbonyl/nitrosyl complexes, (PPh)(CO)Co(NO) (1) and (PPh)(CO)Co(NO) (2), were obtained by reacting (CO)Co(NO) with one equiv. and two equiv. of PPh, respectively.
