2-Amino-4-(4-methoxyphenyl)-7,7-dimethyl-5-oxo-5,6,7,8-tetrahydro-4H-chromene-3-carbonitrile propan-2-one monosolvate

In the crystal structure of the title compound, C19H20N2O3 center dot-C3H6O, molecules are linked into inversion dimers with an R-2(2) (12) motif by pairs of N-H center dot center dot center dot N hydrogen bonds. These dimers are further connected into chains running along the a axis by N-H center dot center dot center dot O hydrogen bonds. C-H center dot center dot center dot N and C-H center dot center dot center dot center dot interactions also feature in the packing. The cyclohexene ring adopts nearly an envelope conformation [puckering parameters are Q(T) = 0.456 (2) angstrom , theta = 54.6 (3)degrees and phi = 225.2 (3)degrees]
