Abstract: N-acetyl-3,3-dinitroazetidine(ADNAZ) and N-formyl-3,3-dinitroazetidine(FDNAZ), acyl derivatives of 3,3-dinitroazetidine(DNAZ) were prepared. Single crystals suitable for X-ray measurement were obtained. ADNAZ crystallizes in the orthorhombic system, space group P212121 with unit cell parameters a=0.6844(3) nm, b=0.6994(3) nm, c=1.6948(6) nm, V=0.8112 nm3 , Z=4. FDNAZ crystallizes in the monoclinic system, space group P21/c with unit cell parameters a=1.0322(4) nm, b=0.6054(2 ) nm, c=1.1268(4) nm, β=100.135(5)°, V=0.6932 nm3, Z=4. The density functional theory(DFT) method of the Amsterdam density functional(ADF) was used to calculate the geometry and frequency of the two derivatives. The geometry, Hishfeld charges of atoms, Mayer bond orders, frontier orbital energy and the main atomic orbital percentage were calculated. The analytical results indicate that the oxygen atom of acyl group is an active atom for ADNAZ and FDNAZ.
