摘要：The title compound (p-methylphenylbis(4, 4-dimethyl-6-hydroxycyclohexene-1-one-2-yl)methane) has been synthesized by the reaction of 4-methylbenzaldehyde and 5, 5-dimethyl-1, 3-cyclohexanedione in N,N-dimethylformamide. Its structure was determined by single crystal X-ray diffraction. The Crystal is monoclinic, space group P21/a, a=0. 9304 (2)nm, b=1. 1754 (2)nm, c=2. 0134 (4)nm, β=102. 40(2)°, Mr= 382. 50, V=2. 1505 (7)nm3, Dc = 1. 181g/cm3, Z=4, μ(MoKα) = 0. 79cm-1, F(000) = 856.The structure was solved by direct methods, and refined by full-matris least-Squares method to a final R =0. 042 and Rw = 0. 045. The crystal structure shows that there are two conjugated enol form in the molecule.
