Abstract
Abstract This study treats about two successfully synthesized secondary amide compounds 3-Acetoxy-2-methyl-N-(phenyl)benzamide, I and 3-Acetoxy-2-methyl-N-(4-methylphenyl)benzamide, II . Compounds were characterized by FTIR, 1 H NMR, 13 C NMR and X-ray single crystal diffraction analysis techniques. Single crystal X-ray diffraction analyses show that while I crystallized in the orthorhombic system with space group Pbca , II crystallized in the triclinic system with space group P-1 and the asymmetric unit of II consists of two crystallographically independent molecules. Lattice constants are a = 7.9713 (3) A, b = 9.5059 (3) A, c = 37.1762 (2) A, Z = 8 for I and a = 7.5579 (8) A, b = 8.8601 (8) A, c = 23.363 (3) A, α = 97.011 (9) °, β = 96.932 (9)°, γ = 90.051 (8)°, Z = 4 for II . Crystallographic studies also show that the supramolecular structures were stabilized by intramolecular, intermolecular hydrogen bonds and C H … π interactions for both compounds. Characteristic amide bonds were observed in IR and NMR spectra.
