چکیده
The title compound, C21H21NO, is a vinyl-ogous amide (enaminone) produced by reaction of 1-(2-phenyl-prop-2-en-1-yl)pyrrolidine-2-thione with phenacyl bromide. In the mol-ecule, the phenyl rings are twisted from the mean plane of the pyrrolidine ring by 11.2 (1) and 67.3 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules related by translation along the b axis into chains.

In the title mol-ecule, C(16)H(13)N(3)O(3), the benzene and phenyl rings are linked through a propenyl-idene hydrazide fragment, C-C(=O)-N(H)-N=C(H)-C(H)=C(H)-, which is fully extended with torsion angles in the range 175.4 (2)-179.9 (2)°. The dihedral angle between the the benzene and phenyl rings is 58.28 (7)°. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules...

The title compound, C21H21N3O2, adopts a J-shaped conformation which appears to be at least partially directed by a weak intra-molecular C-H⋯N hydrogen bond. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into R 2 (2)(8) and R 2 (2)(14) cyclic dimers, which form a chain running parallel to the b axis.

The Co(II) atom in the title monomeric Schiff base complex, [CoCl(2)(C(21)H(22)N(2))], is bonded to two Cl atoms and to two N atoms of the Schiff base ligand N,N'-bis-[(E)-3-phenyl-prop-2-en-1-yl-idene]propane-1,3-diamine in a distorted tetra-hedral geometry. The mol-ecule has an idealised mirror symmetry, but is not located on a crystallographic mirror plane.

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)].

The title compound, C23H21N3O2, is constructed about an almost planar disubstituted amino-urea residue (r.m.s. deviation = 0.0201 Å), which features an intra-molecular amine-N-H⋯N(imine) hydrogen bond. In the 'all-trans' chain connecting this to the terminal meth-oxy-benzene residue, the conformation about each of the imine and ethyl-ene double bonds is E. In the crystal, amide-N-H⋯O(carbon-yl)...
