Novel polystrene-bound Schiff bases and their Pt(IV) complexes have been prepared from condensation reaction of polystyrene-A-NH2 with 2-hydroxybenzaldehyde and 5-fluoro-3bromo-2-hydroxybenzaldehyde. The structures of Pt(IV) complexes with polystyrene including Schiff bases have been determined by elemental analyses, magnetic susceptibility, IR, H-NMR, UV-vis, TG/DTA and AAS. The antibacterial ...

In the title complex, [Zn(C(13)H(16)NOS(2))(2)], the Zn(II) ion is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a distorted trans-ZnN(2)O(2) square-planar geometry for the metal ion.

In the title compound, [Ni(C(13)H(11)N(2)O)(H(2)O)]NO(3)·H(2)O, the Ni(II) ion is coordinated by one O atom and two N atoms of the Schiff base ligand and the O atom from a water mol-ecule, forming a slightly distorted square-planar geometry. A one-dimensional double-chain structure is formed along [001] by O⋯H-O hydrogen bonds and the Ni⋯O [2.617 (3) Å] inter-actions.

In the title compound, [Sn(C(6)H(5))(2)(C(18)H(12)N(2)O(3))], the Sn(IV) atom has a distorted trigonal-bipyramidal geometry. The Schiff base mol-ecule is coordinated to the Sn(IV) atom in a tridentate fashion via the azomethine N atom, the hydr-oxy O atom and the carbonyl O atom. The complex involves an intra-molecular O-H⋯N hydrogen bond.

In the title complex, [Cu(C13H11N2O)(N3)], the Cu(II) cation is four-coordinated by an N2O donor set of the tridentate Schiff base ligand and by the terminal N atom of the azide anion, forming a slightly distorted square-planar configuration.

Conjugated Schiff base macrocycles with wide bores and conformational flexibility bind organic cations in their interiors, and can be used to assemble larger supramolecular structures.

The title compound, C(27)H(19)BrN(4)O, is a mono-anil Schiff base ligand. Three intra-molecular O-H⋯N and N-H⋯N hydrogen bonds involving the hydr-oxy and amino groups generate S(6) and S(5) ring motifs, respectively. In the crystal structure, weak inter-molecular N-H⋯O and C-H⋯O hydrogen bonds together with π-π inter-actions [centroid-centroid distances = 3.628 (3)-3.729 (3) Å] link neighboring...

In the title linear homo-trinuclear complex, [Cd3(C19H18Cl2N2O2)2(C2H3O2)2], the central Cd(II) atom is located on a centre of inversion and has a distorted octa-hedral coordination geometry formed by four O atoms from two bidentate/tetra-dentate Schiff base ligands and two O atoms from two bridging acetate ligands. The coordination geometry of the terminal Cd(II) atom is square-pyramidal with ...

Schiff bases exhibited sensor activity via cyclic voltammetry, colorimetry, and UV-vis study at room temperature. The probes could be employed as a low-cost, ultrasensitive chemo-sensor to detect Cu 2+ Zn in solutions.

Three bidentate Schiff bases having nitrogen and sulphur donor sequences were prepared by condensing S-benzyldithiocarbazate (NH(2)NHCS(2)CH(2)C(6)H(5)) with heterocyclic aldehydes. The reaction of diphenyltin dichloride with Schiff bases leads to the formation of a new series of organotin(IV) complexes. An attempt has been made to prove their structures on the basis of elemental analyses, cond...
