title: cis-3-Methyl-1-phenyl-8a,9,10,11,12,12a,12b-hexa-hydro-1H,3bH-pyrazolo[3,4:2',3']pyrano[4',5',6'-kl]xanthene.
abstract: The asymmetric unit of the title compound, C(23)H(22)N(2)O(2), contains two independent mol-ecules, A and B. The cyclo-hexane ring of mol-ecule B is disordered, with occupancies for the major and minor conformers of 0.570 (9) and 0.430 (9), respectively. The cyclo-hexane ring adopts a boat conformation in mol-ecule A and in the major conformer of mol-ecule B, and a chair conformation in the minor conformer of mol-ecule B. In both independent mol-ecules, one of the dihydro-pyran rings adopts a boat conformation while the other is in a half-chair conformation. The dihedral angle between the pyrazole and phenyl rings is 16.0 (1)° in mol-ecule A and 12.9 (1)° in mol-ecule B. The crystal packing is stabilized by C-H⋯O and C-H⋯N inter-molecular hydrogen bonds.
