The title compound C18H18N2O2 was obtained from benzylidenepropanimine and 5,5-dimethyl-l, 3-cyclohexanone in ethylene glycol for 2 hours. The structure was confirmed by single crystal X-ray diffractometry. The crystal Is a monoclinic with space group P21 / c, Mr = 294.34, a = 11.3070 (1), b = 9.4750 (1), c = 14.919 (2), β = 99.34 3, Z = 4, Dc = 1.240Mgm-3, μ = 0.082mm-1 and F (000) = 624. The final deviation factors are R = 0.0381 and wR = 0.0961. There are three rings in the molecular structure: benzene (A), a pyran ring (B), and a six-membered ring (C) fused to a pyran ring. The dihedral angles between A and B, A and C, and B and C were 92.5 °, 85.7 ° and 8.2 °, respectively.
