In the title mononuclear Schiff base complex, [Dy(NO(3))(3)(C(18)H(20)N(2)O(4))], the Dy(III) ion is ten-coordinated in a distorted hexa-deca-hedral geometry by six O atoms of three nitrate anions and four O atoms of the Schiff base ligand. An intra-molecular N-H⋯O hydrogen bond occurs. The crystal structure is stabilized by inter-molecular C-H⋯O hydrogen bonds.

The title compound, C(15)H(13)N(3)O(4)·CH(4)O, was synthesized from the reaction of 4-methoxy-benzaldehyde with 4-nitro-benzohydrazide in methanol. The benzene rings of the Schiff base mol-ecule are nearly coplanar, making a dihedral angle of 7.0 (3)°. The methanol solvent mol-ecules are linked to the Schiff base mol-ecules by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming chains running parall...

In the title compound, [Na(4)(C(15)H(9)N(4)O(4))(4)(CH(3)OH)(4)], the N(3)O(3) environment around the Na(+) ion is distorted octa-hedral. In the unit cell, four Na(+) ions are bridged by four Schiff base anions, leading to a tetra-nuclear complex with -4 symmetry. O-H⋯N hydrogen bonds between the methanol mol-ecule and the Schiff base anion stabilize the structural set-up.

N-[(1E)-(3-Bromophenyl)methylene]-N-(2-piperidin-1-ylethyl)amine Schiff base was prepared in good yield and characterized by the reflux of equivalent amounts of 2-(piperidin-1-yl)ethanamine with 3-bromobenzaldehyde. The structure of the desired Schiff base was analyzed based on: elemental analysis, EI-MS, TG/DTG, UV-visible, FT-IR, 1H and 13C-NMR spectral analysis. The condensation reaction was...

The asymmetric unit of the title complex, [Cu(C(11)H(16)N(3)O)]ClO(4), consists of two Cu(II) ions coordinated by Schiff base ligands and two perchlorate anions. The Schiff base mol-ecules are linked to the Cu(II) atoms via three N atoms and one O atom, resulting in a square-planar geometry. Inter-molecular hydrogen bonds involving the NH groups as donors and O atoms of the perchlorate anions a...

In the title compound, C(14)H(9)I(2)N(3)O(4)·CH(3)OH, the Schiff base mol-ecule adopts an E geometry with respect to the C=N bond and the dihedral angle between the benzene rings is 45.0 (2)°; an intra-molecular O-H⋯N hydrogen bond is present. In the crystal, adjacent Schiff base mol-ecules are linked by methanol solvent mol-ecules through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming...

The title compound, C(14)H(10)ClN(3)O(4)·CH(4)O, was synthesized from the reaction of 5-chloro-salicylaldehyde with 4-nitro-benzohydrazide in methanol. The Schiff base mol-ecule is nearly planar, with a dihedral angle of 9.1 (3)° between the two benzene rings. The methanol solvent mol-ecules are linked to the Schiff base mol-ecules by N-H⋯O, O-H⋯N and O-H⋯O hydrogen bonds, forming chains runnin...

A family of novel chiral "calixsalen" Schiff base macrocycles R,R-H(3)L4, R,R-H(3)L5, containing three chiral diamino moieties were synthesized by an efficient self-assembly and characterized by (1)H and (13)C NMR, mass spectrometry, and X-ray diffraction. The systematic synthesis, structure, and coordination properties of the [2 + 2] and [3 + 3] Robson-type Schiff base macrocyclic mono-, di-, ...

The title Schiff base complex, [V(C(13)H(7)BrClNO(2))(CH(3)O)O(CH(3)OH)], features a vanadyl group, a tridentate Schiff base ligand, and coordinated methanol and methano-late ligands. The NO(5) donor set is based on a distorted octa-hedron. Helical supra-molecular chains along [010] are found in the crystal structure mediated by O-H⋯O hydrogen bonds formed between the coordinating methanol mol-...

In the title complex, [CuEu(C(19)H(20)N(2)O(4))(NO(3))(3)], the Cu(II) ion is four-coordinated in a square-planar geometry by two O atoms and two N atoms of the deprotonated Schiff base. The Eu(III) atom is ten-coordinate, chelated by three nitrate groups and linked to the four O atoms of the deprotonated Schiff base.
