摘要

Polymorphic transformation temperature of 2,2’:6’,2”-Terpyridine (terpy) has been studied. No transformation was observed for unground terpy (orthrhombic form) crystals, while the ground crystals may be transformed into monoclinic form. The transformation temperature was much lower than reported transformation temperature. In addition the transformation temperature decreased with increase of the grinding time. Factors influencing the transformation temperature of terpy were discussed.
