Abenzophenone substituted semicarbazone, 2-((3-aminophenyl)(phenyl)methylene)hydrazinecarboxamide
(APHC) had been synthesized in good yield by the condensation of
3-aminobenzophenone and semicarbazide hydrochloride. The title compound was
elucidated by elemental analysis (CHN), FTIR, 1H and 13C-NMR, 1H-1H COSY, TGA and single crystal X-ray diffraction. The
compound crystallized in the orthorhombic crystal system with space group of Pccn, Z = 32, V = 10375.1(2) ?3, and lattice constants a = 12.3855(1) ?, b = 34.5746(5) ?, c =
24.2283(3) ? and γ = β = α = 90°. The molecular view
shows that APHC contains four molecules of each species in the asymmetric unit,
with similar geometries. However, there is no intramolecular hydrogen bond
found in the crystal structure of the synthesized compound. X-ray diffraction
also reveals that the molecule of the semicarbazone exists as a Z isomer with respect to the C=N.
