Large volumetric thermal expansion of a novel organic cocrystal over a wide temperature range

Abstract

An organic cocrystal consisting of 4-aminobenzonitrile and 4-(dimethylamino) benzonitrile (ABN·2DMABN) undergoes positive linear thermal expansion along its three principal axes over the temperature range 100–300 K. The associated volumetric thermal expansion coefficient is the largest reported to date for a cocrystal in the wide temperature range investigated.
