Abstract
The title compound, 2,4,9-trimethylpyrido[3,2-c]coumarin, crystallizes in the triclinic space group P1 with the following unit-cell parameters: a = 9.4892(5), b = 10.4245(6), c = 7.7307(4)A, α = 94.556(3), β = 120.824(3), γ = 110.532(3)°, Z = 2. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data, and refined by full-matrix least-squares procedures to a final R-value of 0.0411 for 1658 observed reflections. Molecules are linked into centrosymmetric dimers by means of paired C-H…O hydrogen bonds. The crystal structure is stabilized by a number of π-π stacking interactions.
