چکیده
In the title compound, C(12)H(16)N(2)O(4)·H(2)O, the mol-ecular skeleton of the hydrazinecarboxyl-ate is nearly planar [within 0.053 (3) Å]. In the crystal, chains propagating along the c axis arise, composed of alternating hydrazinecarboxyl-ate mol-ecules and crystalline water, which inter-act via N-H⋯O and O-H⋯O hydrogen bonds.
