Crystal structure and features of 3′,8-dibenzylidene-4a,5,6,7,8,8a-hexahydro-2′H-spiro[chromene-2,1′-cyclohexan]-2′-one
The synthesis and crystal structure of the title compound, C28H28O2, are reported. The C=C—C—C torsion angles in the phenylmethylidene units are 166.6 (3) and −48.0 (4)°. In the crystal, molecules form a three-dimensional network by means of weak C—H...O hydrogen bonds. The most important contributions to the crystal structure are the H...H interactions (68.8%), while the H...O contacts account for 4.5%.
