A new series of transition metal complexes of Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) were synthesized from the Schiff base ligand derived from 4-aminoantipyrine, furfural and o-phenylenediamine. The structural features were derived from their elemental analyses, infrared, UV-visible spectroscopy, NMR spectroscopy, thermal gravimetric analyses, ESR spectral analyses and conductivity measureme...

Co(II) and Ni(II) complexes with a Schiff base, N-(2-furanylmethylene)-2-aminothiadiazole have been prepared and characterized by their physical, spectral and analytical data. The synthesized Schiff-bases act as tridentate ligands during the complexation reaction with Co(II) and Ni(II. metal ions. They possess the composition [M(L)(2)]X(n) (where M=Co(II) or Ni(II), L=, X=NO(3) (-), SO(4) (2-),...

in this paper, cuo nanoparticles  have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem).

A series of coordination compounds have been prepared with tridentate Schiff base ligands, 2 ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-semicarbazone [EHPQS) and 2-ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-thiosemicarbozone [EHPQT]. The obtained complexes were characterized by molar mass, elemental analysis, infrared spectra, electronic spectra, magnetic susceptibility molar conductanc...

A new Schiff base has been synthesized from 3-(3-nitrophenyl)-1-phenyl-1H-pyrazole-4carbaldehyde and O-amino phenol. Metal complexes of the Schiff base have been synthesized from acetate salt of Cu (II), Co (II) and Ni (II) metal in the alcoholic medium. The newly prepared Schiff base ligand and metal complexes have been characterized by various physicochemical techniques such as Elemental anal...

In the title compound, [Mn(NCS)(2)(C(17)H(20)N(4))], the Mn(II) atom is six-coordinated by the N,N',N'',N'''-tetra-dentate Schiff base ligand and by two trans-N atoms from two thio-cyanate anions, forming a distorted octa-hedral geometry. The dihedral angle between the aromatic rings of the Schiff base is 9.5 (3)°.

The pyridine-coordinated Cu(II) atom in the title Schiff base complex, [Cu(C(15)H(11)N(3)O(5))(C(5)H(5)N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.
