| Abstract: | The title compound (C23H25O3Cl) has been synthesized by reaction of o-chlorbenzaldehydeand 5, 5-dimethyl-1, 3-cyclohexanedione in N, N - d imet h ylforma mide and its struc ture was determined by single crystal X-ray diffraction. The crystal is monoclinic, space group C2/c with a=17. 095(3), b= 11. 496(2), c=21. 822(4),The structure was solvedby direct methods, and refined by full-matrix least-squares method to a final R= 0. 054 and RThe crystal structure shows that the dihedral angle between pyranoid ring and phenylring is 92. 43°. |
