Abstract
The crystal structure and structural features of the 7-phenyl-9,11-dihydrochromeno(4,3-b)pyrazolo(4,3-e)pyridine-6(7 H )-one molecule obtained according to the Biginelli reaction in the interaction of 4-hydroxy-2 H -chromen-2-one, benzaldehyde, and 1 H -pyrazole-5-amine are determined by single crystal X-ray diffraction.
