2-aminophenalenone: Crystal data and molecular packing

摘要

Powder diffraction data for 2-aminophenalenone at 295 K(P2_1, z=4) are given, strong lines: 7.54/x, 7.26/9, 3.34/3. The cell parameters found are a=3.7213(3), b=16.550(2), c =15.095(2) A, β=92.61(2). The crystal structure was determined using powder data an refined giving Rb=0.089.Disordered molecules form stacks along [100] with interplanar spacing of 3.48 A.
