7,7′,8,8′-Tetra­meth­oxy-4,4′-dimethyl-3,5′-bichromene-2,2′-dione

In the title mol­ecule, C(24)H(22)O(8), the mean planes of the two coumarin units are inclined to each other at a dihedral angle of 79.93 (3)°. The attached meth­oxy groups form torsion angles of 7.65 (19) and 78.36 (14)° with respect to one coumarin unit, and angles of 9.01 (16) and 99.08 (11)° wit...
