      abstract     = {On-surface molecular functionalization paved the way for
                      the stabilization of chelated ions in different oxidation
                      and spin states, allowing for the fine control of catalytic
                      and magnetic properties of metalorganic networks.
                      Considering two model systems, a reduced Co(I) and an
                      open-shell Co(II) metal-supported 2D molecular array, we
                      investigate the interplay between the low valence oxidation
                      and unpaired spin state in the molecular reactivity. We show
                      that the redox reaction taking place at the cobalt
                      tetraphenylporphyrin/Cu(100) interface, stabilizing the
                      low-spin Co(I) state with no unpaired electrons in its
                      valence shell, plays a pivotal role in changing the
                      reactivity. This goes beyond the sole presence of unpaired
                      electrons in the valence state of the Co(II) metal–organic
                      species, often designated as being responsible for the
                      reactivity towards small molecules like NO and NO2. The
                      reversible Co–NO2 interaction, established with the Co(I)
                      leads to the stabilization of the Co(III) oxidation state.},
