2-hydroxy, 4-amine, w -w', dichloroacetophenone crystalizes in the monoclinic space group P2\\a with unit cell parameters a = 7.458(2), b = 9.109(1), c = 13.3997(26) Äand β = 99°.86(2), Cell vol. = 896.905 Ä 3 , d c = 1.63 g/ml, d a = 1.65 g/ml, μ(ΜοΑΓα) = 6.86 cm" 1 , F 000 = 480 and with four molecules per unit cell. The gross structure was confidently predicted in applying 'Patterson synthesis' method, which yielded R = 0.044 and S = 1.28, S, being the standard deviation of an observation with unit weight.

Crystal structure / OxoethanophenanthreneAbstract. The crystal structure of oxoethanophenanthrene (C 17 H, 8 0) has been determined from three-dimensional X-ray diffraction data collected by Nonius CAD 4 diffractometer with MoATa-radiation.
