Two azafulgides were synthesized and their crystal structures determined by a single crystal X‐ray diffraction analysis. The substances crystallized in the following symmetries and cell parameters. C 23 H 19 NO 3 ( 2 ): triclinic space group P &1bar; with a = 7.243(2). b = 10.981(6) and c = 12.672(8)Å, α = 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 2 v 9 ‐ Pmc 2 1 with a = 8.079(8), b = 12.752(9) and c = 15.752(13)Å, Z =4. The calculated densities are 1.26 and 1.27 g/cm 3 respectively for 2 and 1 . The crystal structures were determined by direct methods. The least‐squares refinement led to R values of 0.044 and 0.058 for 2 and 1 for 2738 and 952 reflections with I > 3σ‐( I ) respectively.
