چکیده
In the non-planar title compound, C(16)H(14)N(2)O(2), the dihedral angle between the phenyl rings is 16.67 (8)°. An E conformation is found for each of the imine [1.286 (2) Å] and ethyl-ene [1.335 (2) Å] bonds. The amide O and H atoms are anti, and an intra-molecular hy-droxy O-H⋯N hydrogen bond is noted. The formation of N-H⋯O(hy-droxy) hydrogen bonds in the crystal packing leads to helical chains along the b axis. Supra-molecular layers in the ab plane are formed as the chains are linked by C-H⋯O inter-actions.

The conformation about each of the imine and ethene bonds in the title hydrazide hydrate, C(16)H(13)ClN(2)O·H(2)O, is E. The hydrazide mol-ecule is approximately planar (r.m.s. deviation of the 20 non-H atoms = 0.172 Å). The most significant twist occurs about the ethene bond [C-C=C-C = 164.1 (5)°] and the dihedral angle formed between the benzene rings is 5.3 (2)°]. In the crystal, the presenc...

The title compound, C(11)H(13)N(3)S, is close to being planar, with a dihedral angle of 9.64 (3)° between the benzene ring and the thio-semicarbazone mean plane, maintained by the presence of π-conjugation in the chain linking the the two systems. In the crystal, N-H⋯S hydrogen bonds form centrosymmetric dimers through a cyclic association [graph-set R(2) (2)(8)].

In the title compound, C(16)H(13)N(3)O(4), the dihedral angle between the terminal benzene rings is 14.02 (7)°. The carbonyl groups are anti with respect to each other, which facilitates their participation in the formation of supra-molecular chains. Each side of the -C(=O)N(H)N(H)C(=O)- residue associates with a centrosymmetrically related mol-ecule, resulting in the formation of essentially f...
