H. Ghorbani and A. Bazgir

Abstract: The asymmetric unit of the title compound, C₁₉H₁₆FN₅O₄, contains two independent molecules. The dihedral angles between the main planes and the fluorophenyl rings in the two molecules are 83.24 (5) and 71.76 (4)°. Weak - stacking interactions may be effective in the stabilization of the crystal structure.
