Abstract

Pyridine and formic acid have been crystallized at differing ratios by both cryocrystallization and compression in a diamond anvil cell. Mixtures of the liquids in 1:1, 1:2, and 1:4 ratios all crystallize at high pressure, while only the 1:1 and 1:4 compositions were crystallized by in situ low temperature capillary crystallization. The 1:2 structure crystallized by high pressure is a previously unknown cocrystal of pyridine–formic acid. For the 1:4 mixture, a new polymorph has been identified at a pressure of 14.2 kbar with a distinctly different structure and bonding pattern to that of the previously reported low temperature form.
