Abstract:The structure of 6-t-butyl-1,2-naphthoquinone-1-oxime was determined by direct methods by the use of MoKagr diffractometer data and was refined toR = 0.12. The crystals are monoclinic:a = 8.32(1),b = 6.70(1),c = 11.14(1) Å, beta = 101(1) °,Z = 2,P21/m. The molecule is crystallographically flat and lies in a mirror plane. Pronounced diffuse scattering on [010] oscillation photographs is caused by disorder in the orientation of thet-butyl group. The compound occurs in the oxime form, and not as a 1,2-nitroso naphthol.
