The title compounds, 3a,9a-trans-9,9a-trans-4,4-dimethyl-9-phenyl-2,3,3a,4,9,9a-hexahydrobenzo[f]indene, C21H24, (I), and 3a,4-trans-3a,9a-cis-9,9a-trans-4-methoxy-9-phenyl-2,3,3a,4,9,9a-hexahydrobenzo[f]indene, C20H22O, (II), are products of the photoinduced electron-transfer reaction of 1,1-diphenyl-1,n-alkadienes. The molecular structures are in good agreement with those proposed from the reaction mechanisms. The central rings of the fused systems of both compounds take chair and boat conformations in (I) and (II), respectively. There are no remarkable short contacts shorter than the sum of the van der Waals radii in the crystals, but some weak C—H...π interactions are found.
