9-[(E)-2-(2-Meth­oxy­phen­yl)ethen­yl]-3,4,5,6,7,9-hexa­hydro-2H-xanthene-1,8-dione

In the title compound, C(22)H(22)O(4), the two cyclo­hexenone rings adopt half-chair conformations, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms by 0.142 (2) and 0.287 (2)Å, respectively. In...

Descripción
Sumario:In the title compound, C(22)H(22)O(4), the two cyclo­hexenone rings adopt half-chair conformations, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms by 0.142 (2) and 0.287 (2)Å, respectively. In the crystal, weak C—H⋯O hydrogen bonds link mol­ecules into chains running parallel to the a axis.
