C11H11N3O4 , Mr = 249.23, triclinic, , a = 5.453(1), b = 22.873(5), c = 4.893(1) Å, a = 94.47(3), b = 96.36(3), g = 86.27(3)º, V = 603.7(8)ų,Z = 2, Dx = 1.371 Mg/m-3,l(Cu Ka1) = 1.54178Å, m = 0.86mm-1, room temperature. The crystal structure of N-isopropyl-2-cyano-3(5'-nitrofuryl) - acrylamide has been determined by Direct Methods and refined to R = 0.086 for 797 observed reflections. The molecules in the crystal are packed at normal van der Waals forces and by an hydrogen bond between N1-H1...02i (N1...02i: 2.910(1)Å), with i=x,y,z+1).
