3,15-Dimeth-oxy-10-methyl-tricyclo-[9.4.0.0]penta-deca-1(11),2(7),3,5,9,12,14-heptaen-8-one.

ABSTRACT: The title mol-ecule, C(18)H(16)O(3), contains three fused rings, of which the seven-membered cyclo-hept-2-enone ring has a screw-boat conformation. The two meth-oxy-phenyl rings make a dihedral angle of 50.4 (2)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds, leading to a three-dimensional supra-molecular architecture.
