Oxidation numbers: (−I) in [Co(CO)
4
]– (II) in Co
2+
, (III) in Co
3+
and (IV) in CoO
2
. In [Co(CO)
3
(NO)] (from a non-aqueous source) we could, without further structural information, classify Co as Co
0
but might also well see it as [Co–(CO)
3
(NO
+
)] in spite of the electronegativities (because NO
+
is isoelectronic with the very stable N
2
and CO), or as [Co+(NO
–
)(CO)
3
], assigning the metal as usual a positive oxidation state. (These assignments, within molecules, are partly but not entirely arbitrary.) Various experiments and calculations, not described here, also reveal NO both as a primarily neutral radical, e.g., in [Ir
3+
(Cl
–
)
5
(NO
+
)] and as NO
+
in [Ru
3+
(Cl
–
)
5
(NO
+
)]. See 6.1.2 and 8.1.2 Oxidized nitrogen also.
