Temperature-Dependent Phase Transition Studies Of Multicomponent Crystals Of Hexamethylenetetramine And Isonicotinamide

Temperature-Dependent Phase Transition Studies Of Multicomponent Crystals Of Hexamethylenetetramine And Isonicotinamide

In this research, thirty-one multi-component crystals of hexamethylenetetramine and isonicotinamide were successfully prepared and seven of them undergo temperature-dependent phase transitions, which were investigated by using variable-temperature single-crystal X-ray diffraction analysis. These se...
