1-aminoanthraquinone: Crystal data and a model of molecular packing

摘要

The powder diffraction data for 1-aminoanthraquinone at 295 K (P1, No.2, Z=1) are given. The cell parameters found ar a=8.205 (1), b=8.396(1), c=3.7882(3)A, α=93.45 (1), β =92.57 (1), γ=105.13(1)°. The crystal packing model is proposed giving R_b=0.095. The disordered molecule of 1-aminoanthraquinone occupies a special position on the inversion center.
