Abstract
Crystal and molecular structure of 3-(2,4,6-trimethylphenyl)-8-phenyl-oxo 1 ,7-dioxa-2-azaspiro[4,4] non-2-ene has been determined by X-ray diffraction technique. Crystal data for C21H21NO3: monoclinic, C2/c, a = 20.969(4) Ang strom, b = 10.319(2) Angstrom, c = 16.601(3) Angstrom, beta = 97.5(3)degree s, Z = 8, R = 0.0658 for 3477 reflections. Contrary to the solution, in the crystalline state only one conformer exists.
