The unit cell of N-tert-butyl-3-(tert-butylimino)-2-nitropropen-1-amine (4) is monoclinic, space group P21/C, with a = 9.669(4), b = 16.415(6), c = 17.341 (7) Å, and Z = 4. Hydrolysis of 4 leads to (E)-3-(N-tert-butylamino)-2-nitro-2-propenal (5), whose unit cell is monoclinic, space group P21/n, with a = 6.821(1), b = 20.707(6), c = 6.303(1)Å, and Z = 4. Compounds 4 and 5 both possess C2 symmetry in the solid state, their “U-shaped” conjugated cores being essentially planar. In each case this planarity is enforced by an intramolecular hydrogen bond.
