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.
