Synthesis, Characterization, and Thermal Investigation of Copper(Ii), Nickel(Ii), Cobalt(Ii), and Zinc(Ii) Complexes With 5-Benzoyl
(Marcel dekker inc, 2003) Sönmez, M; Sekerci, M
Cu(II), Ni(II), Co(II) and Zn(II) complexes of 5-benzoyl-1-(phenylmethylenamino)-4-phenyl-1H-pyrimidine-2-thione were prepared. These complexes have been characterized by elemental analyses, IR, NMR and UV-Vis spectra. Spectral studies, magnetic moment and molar conductivity measurements were performed on these compounds. All of the complexes are non-electrolytes. The metal complexes are proposed to have an octahedral Structure. Thermal Studies of the complexes are also reported.
A New Heterocyclic Schiff Base and Its Metal Complexes
(Marcel dekker inc, 2004) Sönmez, M; Sekerci, M
Cu(II), Co(H), Ni(II), and Zn(II) metal complexes of a new SNO tridentate heterocyclic Schiff base derived from the reaction of 1-amino-5benzoyl-4-phenyl-IH-pyfimidine-2-thione with salicylaldehyde have been synthesized and characterized on the basis of elemental analyses, electronic, IR, and H-1 NMR spectra, and also by molar conductivity measurements, magnetic moment measurements and thermogravimetric analyses (TGA). It has been found that the Schiff base behaves as a neutral tridentate SNO ligand forming chelates with I : 2 or I : I (metal: ligand) stoichiometry. The complexes of Co(II), Ni(II), and Zn(II) are proposed to have an octahedral structure, while the Cu(II) complex is suggested to have a square-pyramidal geometry. All of the complexes show nonelectrolytic behavior.
Synthesis, Characterization, and Thermal Investigation of Some Metal Complexes Containing Polydentate Ono-Donor Heterocyclic Schiff Base Ligand
(Maik Nauka/interperiodica, 2004) Sönmez, M; Levent, A; Sekerci, M
Cu(II), Co(II), Ni(H), and Zn(II) metal complexes with new heterocyclic Schiff base derived from 1-amino-5-benzoyl-4-phenyl-IH-pyrimidine-2-one and 3-methoxysalicylaidehyde have been synthesized and characterized on the basis of elemental analyses, electronic IR, and H-1 NMR spectra, and also by aid of molar conductivity measurements, maenetic moment measurements, and thermogravinietric analyses. It has been found that the Schiff base behaves as a neutral bidentate (NO) and tridentate (ONO) ligand forming chelates with 1 : 2 (metal : ligand) stoichiometry. Octahedral configuration is suggested for metal complexes. The conductivity data for the Ni(II) complexes are consistent with those expected for a 1 : 2 electrolyte.
Synthesis and Characterization of Cu(Ii), Co(Ii), Ni(Ii), and Zn(Ii) Complexes of a Schiff Base Derived From 1-Amino and 3-Hydroxysalicylaldehyde
(Taylor & Francis inc, 2003) Sönmez, M; Levent, A; Sekerci, M
Cu(II), Co(II), Ni(II) and Zn(II) metal complexes of a new beterocylic Schiff base derived from 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one with 3-hydroxy-salicylaidehyde have been synthesized and characterized on the basis of elemental analyses, electronic, IR and H-1 NMR spectra, molar conductivity measurements, magnetic moment measurements and thermogravimetric analyses (TGA). It has been found that the Schiff base behaves as a neutral bidentate (NO) or tridentate (ONO) ligand forming chelates with 1:2 (metal:ligand) stoichiometry and octahedral geometry. The conductivity data for the Ni(II) complex is consistent with that expected for a weak electrolyte.

(Polish Chemical Society, 2002) Sönmez, M; Sekerci, M
Cu(II), Co(II), Ni(II) and Zn(II) metal complexes of new heterocyclic Schiff base derived from 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one with salicylaldehyde have been synthesized and characterized by elemental analyses, mass, electronic, IR and H-1 NMR spectra, and also by molar conductivity measurements, magnetic moment measurements and thermogravimetric analyses (TGA). It has been found that the Schiff bases behave as a neutral bidentate (NO) and tridentate (ONO) ligands forming chelates with 1:2 (metal:ligand) stoichiometry. Octahedral environment is suggested for metal complexes. The conductivity data for the Ni(II) complexes are consistent with those expected for an electrolyte.
