2,5-Bis(4-methylphenyl)-7-phenyl-6,7-dihydropyrazolo[1,5-a]pyrimidine-3,6-dicarbaldehyde: hydrogen-bonded sheets built from N—H...O and C—H...O hydrogen bonds (original) (raw)

2,5-Bis(4-methylphenyl)-7-phenyl-6,7-dihydropyrazolo[1,5-a]pyrimidine-3,6-dicarbaldehyde has been synthesized and characterized, revealing its structure and the significant influence of hydrogen bonding in forming complex molecular sheets. The study showcases the arrangement of hydrogen bonds, including N–H...O and C–H...O interactions, that contributes to the stability and conformation of the crystalline form. This work highlights potential applications of fused pyrazole systems in developing biologically active compounds.
