摘要: Novel p-xylylene-bis(thioacetic) acid (p-XBTA) and its co-crystals with 2-amino-4,6-dimethylpyrimidine (DMP) have been synthesized characterized by single-crystal X-ray diffraction, infrared spectroscopy thermal analysis methods (TG/DSC). Depending on the crystallization conditions, three different multicomponent crystal forms isolated various chemical compositions stoichiometries of co-formers. The ATR-FTIR spectra display stretching vibration bands for co-formers associated shifts confirming formation new phases. DSC TG were used to reveal relative stabilities solids compared those
