Abstract: The heat of combustion and the enthalpy of formation of 7,7'-bis(terfurazan [3,4-$b$:3,4'-$d$:3",4"-$f$]azepine (I) and 1,1'-dioxide-7,7'-bis (terfurazan [3,4-$b$:3,4'-$d$:3",4"-$f$]azepine (II), were experimentally determined. Product I was studied by X-ray diffraction analysis, and its crystallographic characteristics were determined. The efficiency of using compounds I and II as components of solid composite propellant was analyzed, and it was found in what type of compositions they are more effective than HMX.

Keywords: 7,7'-bis(terfurazan [3,4-$b$:3,4'-$d$:3",4"-$f$]azepine (I), 1,1'-dioxide-7,7'-bis (terfurazan [3,4-$b$:3,4'-$d$:3",4"-$f$]azepine (II), enthalpy of combustion, enthalpy of formation, crystal structure, solid composite propellant (SCP), specific impulse.
