Two azafulgides were synthesized and their crystal struetures determined by a single crystalX-ray diffraction analysis. The substances crystallized in the following symmerries and cell parameters.C_(23)H_(19)NO_3(2): triclinic space group P with a=7.243(2), b=10 . 981(6) and c=12. 672(8), a=80.40(5) °,β=75.58(4)° and γ= 77.32(3)°, Z=2; C_(19)H_(19)NO_3(1): orthogonal space group C_(2v)~9-Pmc2_1with a=8.079(8), b=12.752(9) and c=15.752(13), Z=4. The calculated densities are 1.26 and1.27 g/cm~3 respectively for 2 and 1. The crystal structures were determined by direct methods. Theleast-squares refinement led to R values of 0.044 and 0.058 for 2 and I for 2738 and 952 reflections withI>3σ(1) respectively.
