The species reported in Figure are network products in at least one -but not necessarily all -of the four conditions considered (see Supplementary Information for details). We note that we add one additional constraint to the products reported here: spin multiplicity. While open-shell species can be products of the network, they are highly unlikely to be stable or meta-stable (long-lived radicals are generally rare). In the hopes of extracting useful chemical insights from network products, we therefore only consider network products that are singlets.
