Abstract
Synchrotron data allowed the crystal structure determination of 4,4,6,6-tetraphenylcyclohex-2-en-1-one (1). The cyclohexenone ring is in a half-chair conformation 3H2violating the planarity of a conjugated π-system. The geometry of 1 optimized with semiempirical and density functional theory calculations is in good agreement with the experimental data. Compound 1 crystallizes in triclinic space group \(P\overline 1\) with unit cell parameters a = 9.7995(19) Å, b = 10.5263(32) Å, c = 12.2001(37) Å, α = 96.916(10)°, β = 112.971(10)°, γ = 102.589(10)°, V = 1100.86(17) Å3, and Z = 2.
