2,4-Bis(2-methyl-phen-yl)-3-aza-bicyclo[3.3.1]nonan-9-one O-methyl-oxime.

ABSTRACT: The mol-ecule of the title compound, C(23)H(28)N(2)O, exists in a twin-chair conformation, with equatorial orientation of the ortho-tolyl groups on both sides of the secondary amino group. The title oxime compound and its ketone precursor 2,4-bis-(2-methyl-phen-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one exhibit similar stereochemistries, with the orientation of the o-tolyl rings almost identical in both compounds. In the title compound, the tolyl rings are at an angle of 23.77 (3)° with respect to one another; the angle in the precursor is 29.4 (1)° [Vijayalakshmi, Parthasarathi, Venkatraj & Jeyaraman (2000 ▶), Acta Cryst. C56, 1240-1241]. The cyclo-hexane ring and the oxime ether are disordered over two alternative orientations, with a refined site-occupancy ratio of 0.813 (2):0.186 (4). The cr
