Abstract

The crystal and molecular structure of the title compound has been determined by direct methods, and refined to a final R of 0.070 for 1466 observed reflections. The compound crystallizes in space group P2(1)/n with cell dimensions a = 10.706(8), b = 21.127(11), c = 12.038(10)Angstrom, Z = 4.1,4-dihydropyridine ring adopts a boat shaped conformation. The flavon molecule is planar and it's phenyl ring is almost perpendicular to the 1,4-DHP. The C36 atom of the allyl group shows disorder.
