Abstract
The title compound (9-ethyl-9H-carbazol-3-yl)-carbamic acid tert-butyl ester was prepared from 3-amino-9-ethylcarbazole and di-tert-butyldicarbonate (Boc anhydride) in good yield. It was characterized by elemental analysis, FT-NMR, FT-IR spectroscopy and subjected to single crystal X-ray diffraction studies. The compound crystallizes in monoclinic space group P21/c with unit cell dimensions are a = 13.5218(8) A, b = 12.7624(7) A, c = 10.1352(6) A, β = 100.784(6)°, V = 1718.15(17) A3, D x = 1.200 Mg m−3, and Z = 4. According to X-ray diffraction studies the molecule is in a non planar conformation except for the carbazole moiety and having a dihedral angle of 30.239(89)° between the plane of the carbazole and amide moieties. The molecules are packed in a zig-zag manner and strong N–H···O [C(4) motif] intermolecular hydrogen bonding, weak C–H···π [C(5) motif] and π–π stacking interaction stabilize the crystal packing. The thermal analysis of single crystal was determined by DSC and TGA.
