In the title complex, [Ni(C(14)H(9)N(2)O)(2)], the Ni(II) atom lies on an inversion center and is coordinated by the O atom and an N atom of two Schiff base 2-(3-cyano-phenyl-imino-meth-yl)phenolate ligands in a square-planar geometry. The dihedral angle between the cyano-phenyl and phenolate rings is 47.62 (7)°.

In the title compound, [Ni(C(13)H(16)NOS(2))(2)]·CH(3)CN, the Ni(II) atom is four-coordinated by two N,O-bidentate Schiff base ligands, resulting in a distorted tetra-hedral coordination for the metal ion.

In the title compound, [Fe(C(14)H(12)NO)(3)], the Fe(III) atom has a slightly distorted octa-hedral geometry and is coordinated by three Schiff base ligands, viz. 2-(benzyl-imino-methyl)-phenolate. The crystal structure is stabilized by intra-molecular C-H⋯O and C-H⋯N hydrogen bonds.

The mol-ecule of the title compound, [Mn(NCS)(2)(C(16)H(18)N(4))], has crystallographic twofold rotation symmetry, with the Mn(II) atom lying on the rotation axis. The Mn(II) atom is six-coordinated by four N atoms of the Schiff base ligand and by two N atoms of two thio-cyanate ligands, forming a distorted octa-hedral geometry.

A series of mononuclear lanthanide complexes with chiral Schiff base ligands [Ln(FTA)(3)L] [Ln = Dy(1), Sm(2), Eu(3), Gd(4), and Tb(5), L = (S,S)-2,2'-Bis(4-benzyl-2-oxazoline)] were synthesized and characterized. Among these complexes, complex 1 represents the first example of mononuclear lanthanide complexes displaying single-ion magnet behavior and ferroelectricity.

This work addresses and enlightens synthetic aspects derived from our effort to systematically construct isoskeletal tetranuclear coordination clusters (CCs) of the general formula [TR2Ln2IJLX)4IJNO3)2IJsolv)2] possessing a specific defected dicubane topology, utilizing various substituted Schiff base organic ligands (H2LX) and Ni /Co and DyIJOTf)3 salts. Our synthetic work is further supported...

In the title compound, [Fe(C(11)H(13)ClNO)(2)], the Fe(II) atom is four-coordinated in a square-planar geometry by the O and N atoms of two 2-(butyl-imino-meth-yl)-4-chloro-phenolate Schiff base ligands.

A new tetradentate Schiff base-like ligand H2L (1) ((E,E)-dimethyl-2,2′-[1,2-phenylenebis(aminomethylidyne)]bis[3-oxobutanoate]) was synthesised and structurally characterised. Its reaction with iron(II) acetate leads to the formation of the octahedral N2O4-coordinated complex [FeL(MeOH)2] (2). The complex is a pure high-spin (HS) compound as is evident from magnetic measurements and X-ray crys...

Investigations on a series of eight novel mononuclear iron(III) Schiff base complexes with the general formula [Fe(L(5))(L(1))]·S (where H(2)L(5) = pentadentate Schiff-base ligand, L(1) = a pseudohalido ligand, and S is a solvent molecule) are reported. Several different aromatic 2-hydroxyaldehyde derivatives were used in combination with a non-symmetrical triamine 1,6-diamino-4-azahexane to sy...

Mixed ligands biologically active complexes of cobalt(II), copper(II) and nickel(II) with nicotinoylhydrazine-derived ONO, NNO and SNO donor schiff-base ligands having the same metal ion but different anions such as sulphate, nitrate, oxalate and acetate have been synthesised and characterised on the basis of their physical, analytical and spectral data. In order to evaluate the role of anions ...
