Abstract Three new acyl hydrazone compounds C 12 H 12 N 4 O 3 (I), C 12 H 14 N 4 O 4 (II) and C 16 H 16 N 4 O 3 (III) are synthesized and characterized by elemental analysis and single-crystal X-ray diffraction. The crystal structural analyses show that the three compounds crystallize in the monoclinic crystal lattice. Their thermal decomposition processes under nitrogen and air are studied by TG-DTG, the sequence of the ...
