Ni(II), Cu(II), and Zn(II) complexes of tetradentate schiff base containing two thiadiazoles units: Structural, spectroscopic, magnetic properties, and molecular modeling studies
(0-Belirlenecek, 2008)
Four new mononuclear metal complexes with a mononucleating Schiff base ligand containing two thiadiazoles units have been synthesized. The ligand and metal complexes were characterized by elemental analyses, IR, 1H, and ...
Binuclear transition metal complexes of a novel lateral ?N-methylthiosemicarbazone through the central ethylene bridge: Synthesis, structural characterization and the response of ligand molecule to different solvent media
(Elsevier, 2008)
The condensation of 2,2?-(2,3-bis((1-formylnaphthalen-2-yloxy)methyl)but-2-ene-1,4-diy l)bis(oxy)di-1-naphthaldehyde with 4-methyl thiosemicarbazide gave a novel N-methylthiosemicarbazone and then the reaction of this ...
Synthesis and antimicrobial evaluation of novel di-triazoles and 4-arylidene amino 4,5 dihydro-1H-[1,2,4] triazole-5-one derivatives
(0-Belirlenecek, 2008)
A series of novel di-[3(thiophen-2-yl-methyl)-4,5-dihydro-1H-[1,2,4] triazole-5-one-4yl]n-alkanes (2a-h) were obtained by the reaction of N'-1-ethoxy-2-thiophen-2-yl-ethylydene hydrazino carboxylic acid ethyl ester (1) and ...
Microwave-assisted synthesis and characterization and theoretical calculations of the first example of free and metallophthalocyanines from salen type Schiff base derivative bearing thiophen and triazole heterocyclic rings
(0-Belirlenecek, 2007)
Novel metal-free and metallophthalocyanine complexes of Co, Ni, Cu, and Zn have been synthesized by exposure to microwave irradiation and reflux conditions and the products purified by several techniques. The newly prepared ...
Spectroscopic and theoretical study of 1,2,4-triazole-3-one based salicylaldimine complexes and evaluation of superoxide-scavenging properties
(0-Belirlenecek, 2009)
Five mononuclear metal complexes of Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) have been synthesized with a triazole-based Schiff base ligand, 4-{[(1E)-(2-hydroxyphenyl)methylene]amino}-5-(2-thienyl-methyl)-2,4-dihydro-3 ...
Two novel macroacyclic schiff bases containing bis-N2O2 donor set and their binuclear complexes: synthesis, spectroscopic and magnetic properties
(0-Belirlenecek, 2009)
Herein, we report two novel macroacyclic Schiff bases derived from tetranaphthaldehyde derivative compound and their binuclear Mn(II), Ni(II), Cu(II) and Zn(II) complexes. The structures of the compounds have been proposed ...
The microwave-assisted synthesis and structural characterization of novel, dithia-bridged polymeric phthalocyanines containing a substituted thiophenylamine Schiff base
(0-Belirlenecek, 2009)
Novel polymeric metal-free and metallo(Cu(II), Co(II), Ni(II), Zn(II) and Pb(II))-phthalocyanine complexes were synthesized using microwave irradiation and the products were purified by several (crystallization and preparative ...
Synthesis and antimicrobial and antitumor activity of some new [1,2,4] triazole-5-one derivatives
