Abstract

The crystal and molecular structure of the equimolar molecular complex of sernicarbazide with nitric acid has been determinated by X-ray diffraction method. The crystals are orthorhombic, space group P2r2t21 with cell parameters (I = 12.83 I), b = 8.62(1), c = 4.76(3)A and four formal molecules per unit cell. The structure was solved by direct methods and refined by full-matrix least-squares to the final R = 0,161 for 414 visually estimated intensities collected on a Weissenberg camera. In the crystals both the semicarbazide and nitric acid molecules exist in ionic form [HzNCO NHNH; NO;] and intermolecular hydrogen bonds are formed.
