摘　　要：The crystal structure of the title compound,C21H25N7O7,has been determined in the orthorhombic space group C222（1） with a=8.993（10）,b=12.149（14）,c=22.20（2）A and Z=4.There exist intramolecular C-H…O and N-H…N hydrogen bonds in the title crystal structure.The intermolecular N-H…N and C-H…O hydrogen bonds together with π-π stacking interactions（face-to-face） link the molecules into an infinite three-dimensional supramolecular network.The crystal structure of the title compound,C21H25N7O7,has been determined in the orthorhombic space group C222（1） with a=8.993（10）,b=12.149（14）,c=22.20（2）A and Z=4.There exist intramolecular C-H…O and N-H…N hydrogen bonds in the title crystal structure.The intermolecular N-H…N and C-H…O hydrogen bonds together with π-π stacking interactions（face-to-face） link the molecules into an infinite three-dimensional supramolecular network.
