A general experimental procedure of the alkali-BTC coordination network preparation involved the reaction of 1,3,5-benzenetricarboxylic acid (H3BTC) with an alkali hydroxide (MOH, where M = Li, Na, K) in water, yielding an aqueous solution of the M3BTC salt, which was then used for crystallisation of alkali-BTC coordination networks upon introduction of an alcohol as antisolvent.
