Bis{(E)-N'-[2,4-bis(trifluoro-meth-yl)benzyl-idene]isonicotinohydrazide} monohydrate.

ABSTRACT: The asymmetric unit of the title compound, 2C(15)H(9)F(6)N(3)O·H(2)O, contains two independent Schiff base mol-ecules and one water mol-ecule. Both Schiff base mol-ecules exist in an E configuration with respect to the C=N double bonds and the dihedral angles between the benzene and the pyridine rings in the two mol-ecules are 17.53?(12) and 20.62?(12)°. In the crystal structure, mol-ecules are linked by inter-molecular N-H?O and C-H?O hydrogen bonds into infinite one-dimensional chains along the a axis. In addition, inter-molecular O-H?N, O-H?F, C-H?F and C-H?O hydrogen bonds further link these chains into a three-dimensional network. Weak ?-? inter-actions with centroid-centroid distances in the range 3.6495?(17)-3.7092?(16)?Å are also observed.

Project description:The mol-ecule of the title Schiff base compound, C(18)H(12)Cl(2)F(6)N(2), adopts an E configuration with respect to the azomethine C=N bond. Intra-molecular C-H?F (× 2) and C-H?Cl (× 2) hydrogen bonds generate S(5) ring motifs. The imino group is coplanar with the aromatic ring. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the methyl-ene bridge, as indicated by the dihedral angle between the two benzene rings of 3.74?(6)°. The inter-esting features of the crystal structure are weak inter-molecular Cl?N and F?F inter-actions, with distances of 2.9192?(11) and 3.2714?(10)?Å, respectively, which are shorter than the sum of the van der Waals radii of the relevent atoms. These inter-actions link neighbouring mol-ecules into dimers which are stacked down the b axis.

Bis{4-[(Z)-N'-(4-hydroxy-benzyl-idene)hydrazino]-8-(trifluoro-meth-yl)quinolinium} sulfate dihydrate.

Project description:The title compound, 2C(17)H(13)F(3)N(3)O(+)·SO(4) (2-)·2H(2)O, crystallizes with four independent cations (A, B, C and D) in the asymmetric unit, which is composed of two groups of two cations, one anion and two water mol-ecules (Z' = 2).

The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonding between H atoms from 4-hydroxy-phenyl O atoms and the O atoms of nearby water molecules and sulfate anions, as well as H atoms from the N atom of the hydrazino group to O atoms of neighboring sulfate anions, linking the components into chains with the 4-hydroxy-phenyl and quinolinium rings parallel to the (011) plane. There is also an extensive array of inter-molecular hydrogen bonds between water mol-ecules themselves and with sulfate O atoms, as well as hydrogen-bond inter-actions between H atoms from the hydrazino group and sulfate O atoms. In addition, inter-molecular π-π stacking inter-actions occur between nearby 4-hydroxy-phenyl and quinolinium groups, with distances between the centroids of inter-acting rings in the range 3.4140 (9)-3.9659 (9) Å.
