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

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.
