Abstract: The crystal structure of 1H,4H-tetrahydro-8-methyl-quinolizino-(9,9a,1gh)coumarin (C16H17NO2) has been determined by X-ray crystallographic techniques. The compound crystallizes in monoclinic space group P21/n with unit cell parameters: a = 8.657(5) Å, b = 10.251(5) Å, c = 14.508(5) Å, = 96.61(1)°, Z = 4, V = 1278.91(11) Å3. The structure has been solved by direct methods and refined upto reliability index of 4.8%. The fused benzene and pyrone rings are planar. Both the piperidine rings exist in distorted sofa conformation. The crystal structure is stabilized by C-H...O hydrogen bonds.
