Crystal structure of 6-amino-3-methyl-4-phenyl-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile Sharma, Naresh Karmakar, Indrajit Brahmachari, Goutam Gupta, Vivek Kumar Carbonitrile Direct methods Dihydropyrano Hydrogen bonding Biological properties X-ray crystallography The crystal structure of the title compound, 6-amino-3-methyl-4-phenyl-2,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile, were determined by single crystal X-ray structure analysis. The compound C14H12N4O crystallizes in the triclinic crystal system with the P-1 space group (no. 2), having unit cell parameters a = 6.4788(7) Å, b = 8.8433(7) Å, c = 10.7377(9) Å, α = 103.456(7)°, β = 99.207(8)°, γ = 92.451(8)°, V = 588.55(9) Å3, Z = 2. The crystal structure was solved by direct methods using single-crystal X-ray diffraction data collected at room temperature and refined by full-matrix least-squares procedure with a final R-value of 0.0464 for 1432 observed reflections. The dihedral angle between the pyran ring and the pyrazole ring is 178.08(6)°, between the pyrazole ring and the benzene ring is 98.92(6)° and between the pyran ring and the benzene ring is 97.10(5)°. The molecules in the crystal are linked to an infinite two-dimensional network by N−H···N and C−H···π types of hydrogen bonds. Molecules are also reinforced by the π···π interaction between the pyrazole ring and the pyran ring, respectively.
