2-Cyclo­pentyl­idenehydrazine­carboxamide

The asymmetric unit of the title compound, C₆H₁₁N₃O, consists of two independent mol­ecules in which the cyclo­pentane rings adopt envelope conformations with CH₂ grouping as the flap and the semicarbazone groups are essentially planar, with maximums deviation of 0.0311 (12) and 0.0285 (12) Å. In the crystal, N—H...O, N—H...N and C—H...O hydrogen bonds link the mol­ecules to form sheets lying parallel to the ab plane.
