Beyond serendipity: uncovering novel ratiometric urea·24DHBA cocrystals through mechanochemistry and MicroED
{{output}}
Mechanochemical synthesis of urea cocrystals with 2,4-dihydroxybenzoic acid (24DHBA) reveals two new stoichiometric forms: (urea)2·(24DHBA) and (urea)2·(24DHBA)2, not accessible via solution methods. The known (urea)0.5·(24DHBA) form remains the most stable... ...
