(4Z,6Z)-4,6-Bis(4-meth-oxy-benzyl-idene)-2,2-dimethyl-1,3-dioxan-5-one.

ABSTRACT: The title compound, C(22)H(22)O(5), crystallizes with two independent mol-ecules in the asymmetric unit, both of which possess pseudo-C(s) symmetry. The central 1,3-dioxanone rings have envelope conformations, with the C atom bearing the two methyl groups at the flap. The benzene rings of the meth-oxy-benzyl-idene units, attached in the 4- and 6-positions on the central 1,3-dioxanone rings, are tilted in the same direction with dihedral angles varying between 8.2?(1) and 18.1?(1)°. The crystal packing is influenced by ?-stacking inter-actions of the parallel displaced type [centroid-centroid distance of 3.723?(1)?Å for mol-ecule 1 and 3.884?(1)?Å for mol-ecule 2, with ring slippages of 1.432 and 1.613?Å, respectively] and the T-shaped type, with the long mol-ecular axes all aligned along [010].
