| 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. |
