title: 4-Eth-oxy-benzohydrazide.
abstract: The title compound, C(9)H(12)N(2)O(2), is approximately planar (r.m.s. deviation = 0.13 Å for all non-H atoms). The carbonyl O atom is involved as acceptor in three different hydrogen-bond inter-actions. One N-H⋯O and the C-H⋯O(carbonyl) contact together with a weak C-H⋯O(eth-oxy) interaction link the mol-ecules into sheets parallel to (102). These are further linked into a three-dimensional network via the remaining C-H⋯O(carbon-yl) hydrogen bond and a C(methyl-ene)-H⋯π inter-action.
