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.

The asymmetric unit of the title compound, [Ni(C(12)H(18)N(2)O(2))(2)](ClO(4))(2), consists of one-half of a centrosymmetric mononuclear Schiff base nickel(II) complex cation and one perchlorate anion. The Ni(II) ion, lying on the inversion center, is coordinated by two N atoms and two O atoms from two Schiff base ligands, forming a square-planar geometry. The crystal packing is stabilized by N...

The title Schiff base complex, [ZnI(2)(C(16)H(24)N(2)O(2))], is a mononuclear zinc(II) compound. The Zn atom is four-coordinated in a distorted tetra-hedral geometry by one phenolate O atom and one imine N atom of the Schiff base ligand and by two iodide ions. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains running along the a axis.

Photostabilization of functional polymeric materials is important for protection against aging and ultraviolet (UV) irradiation. There is, therefore, the impetus to modify polymers increase their resistance photodegradation photooxidation on extended exposure UV light in harsh conditions. Various additives have been designed synthesized recent years, potential as photostabilizers has explored. ...

In the title Schiff base complex, [Zn(C(14)H(9)Br(2)FNO)(2)], the Zn(II) atom is located on a twofold rotation axis and is coordinated by two O and two N atoms from two symmetry-related bidentate Schiff base ligands in a compressed tetrahedral geometry. The bond lengths and bond angles are within normal ranges. The dihedral angle between the least-squares planes of the aromatic rings within eac...

The title complex, [Cu(C(12)H(16)NO(3))(2)], adopts a distorted square-planar coordination geometry with the Cu(II) ion situated on a crystallographic inversion center. The two Schiff base ligands are coordinated in a trans fashion. In the crystal structure, non-classical inter-molecular C-H⋯O hydrogen bonds involving the ether O atoms link the Schiff base mol-ecules into a two-dimensional netw...

In the title complex, [CuEr(C(19)H(20)N(2)O(4))(NO(3))(3)]·CH(3)COCH(3), the Cu(II) ion is coordinated in a square-planar environment by two O atoms and two N atoms of a Schiff base ligand. The Er(III) ion is bis-chelated by three nitrate ligands and coordinated by four O atoms of the Schiff base ligand in a slightly distorted bicapped square-anti-prismatic environment.
