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 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...
