    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.

    ABSTRACT: In the title compound, C(18)H(19)FN(2)O, the hydrazide side chain is approximately perpendicular to the central ring [dihedral angle = 76.80 (5)°]. The F atom is disordered over two positions with occupancies of 0.818 (2) and 0.182 (2). The packing consists of chains of mol-ecules parallel to the a axis, connected by a bifurcated N-H⋯(O,N) hydrogen bond and a weak C(phen-yl)-H⋯O hydrogen bond. The packing is extended to a layer structure parallel to the ab plane by a weak C(phen-yl)-H⋯F hydrogen bond.

    ABSTRACT: The title compound, C(17)H(19)N(3)O(3)S, crystallizes with two closely similar independent mol-ecules related by a pseudotranslation of c/2. Each mol-ecule consists of three approximately planar moieties centred on the N(2)CS group and the two ring systems. The packing involves classical H bonds of the form N(amide)-H⋯S and N(hydrazine)-H⋯OC, together with various weak hydrogen bonds and N(hydrazine)-H⋯π inter-actions. The overall packing is three-dimensional, but layer substructures parallel to the xz plane can be readily identified. Each mol-ecule forms a topologically equivalent set of hydrogen-bond inter-actions.
