**3. Results and Discussion**

Six new phases were obtained for (lid) and (lidhcl) with hydroquinone, resorcinol, and pyrogallol. Only the phases with (lidhcl) demonstrated improved stability; accordingly, the physical characterisation is focused on these three new phases, after which the six phases are characterised structurally in order to study this stability differences. In all the cases, the correspondence between the SCXRD solved structures and the bulk powder was confirmed by PXRD (see Supplementary Figure S1).
