Crystal structure of α-cyanoacetohydrazide

Abstract

Crystals of the title compound are monoclinic with a= 7·459(6), b= 8·694(7), c= 7·915(6)Å, β= 116·6(5)°, space group P2₁/c and Z= 4. The structure was determined from diffractometer data by symbolic addition procedures, and refined by least-squares methods to R 0·058 for 609 independent reflections. Hydrogen atom positions were also refined. Bond distances are NC 1·122(5), C(sp)–C(sp³) 1·453(5), C(sp³)–C(sp²) 1·524(5), C(sp²)–N 1·330(5), N–N 1·411(5), and CO 1·224(4)Å. The molecules are held together by hydrogen bonds.
