Later related reactions of iridium nitrosyl complexes of a slightly different type were reported (equations 40-42). 

It is remarkable that not a single example of a rhodium or iridium nitrosyl with a Tp ligand has been reported. In a similar manner, analogues based on arenediazenido and thionitrosyl ligands have yet to appear for group 9 metals, despite such compounds being reported for earlier transition metal centres. 

Energetic behavior of the metal d and nitrosyl jt levels on bending the M-N-O unit. Adapted from Reference [54], the extended Hiickel calculation refers to an iridium nitrosyl species. 

The reaction of nitrosyl complexes with Na ions is not limited to coordination complexes of particular metal ions. Instead, the reaction seems to be specific for compounds containing nitrosyl ligands exhibiting electrophilic reactivity, i.e. the linear nitrosyls. As discussed above, sodium nitroprusside37 and iridium nitrosyls react with azide ion in the same manner as ruthenium(II) nitrosyls.
