The size-dependent reactivity of cobalt tropocoronands
[TC-n,n]2– is
manifest in
the NO chemistry of the cobalt(III) nitrite complexes [Co(η2-NO2)(TC-n,n)]
(n = 4–6), the synthesis and characterization
of which are reported for the first time. Complete conversion of [Co(η2-NO2)(TC-4,4)] to the cobalt mononitrosyl [Co(NO)(TC-4,4)]
occurs upon exposure to NO(g). In contrast, addition of NO(g) to [Co(η2-NO2)(TC-5,5)] generates both cobalt mono- and
dinitrosyl adducts, and addition of nitric oxide to [Co(η2-NO2)(TC-6,6)] converts this complex to the dicobalt
tetranitrosyl species [Co2(NO)4(TC-6,6)]. In
the latter complex, two tetrahedral cobalt dinitrosyl units are bound
to the aminotroponeiminate poles of the [TC-6,6]2– ligand. These results significantly broaden the chemistry of cobalt
tropocoronands with nitric oxide and the nitrite anion.
