Synthesis and Characterization of Co(II), Ni(II), Cu(II), and Zn(II) Complexes with a New vic-Dioxime (E,E)-N′-Hydroxy-2-(Hydroxyimino)-N-(4-{[(2-Phenyl-1,3-Dioxolan-4yl)Methyl]Amino}Butyl)Ethanimidamide¹

Synthesis of New Glyoxime Derivatives, Characterization and Investigation of Their Complexes with Co(II), Ni(II), and Cu(II) Metals and Thermal Studies

“…The (-CH 2 ) protons adjacent to the oxime groups were observed around 1.51-3.42 ppm. Also chemical shifts of (H-C=N) protons were observed around 7.92-7.95 ppm [15][16][17][18][19]. In the 13 C NMR spectrum, carbon resonances of the dioxime groups were observed around 138.89-154.38 ppm, as expected for (E,E) dioximes [25].…”

“…In our previous studies, we presented the synthesis and characterization of various transition metal complexes of novel vic -dioximes [13][14][15][16][17][18][19][20]. In the present paper, we report the synthesis and characterization of 1 The text was submitted by the authors in English.…”

“…The geometrical isomers of vic -dioximes and their derivatives, depending on the position of the OH groups in the molecule, are syn , anti and amphi structures [10]. Usually, the stability order of these is anti > amphi > syn configuration [11] but there are some exceptions [12].In our previous studies, we presented the synthesis and characterization of various transition metal complexes of novel vic -dioximes [13][14][15][16][17][18][19][20]. In the present paper, we report the synthesis and characterization of 1 The text was submitted by the authors in English.…”

Synthesis of novel tetraoxime derivative with hydrazone side groups and its metal complexes

“…The electronic absorption spectrum of the Zn(II) complex showed an absorption band at 455 nm attributed to the L → M charge transfer transition, which is compatible with this complex having a tetrahedral structure. 33,34…”

Synthesis and Characterization of Mononuclear Cobalt(II), Nickel(II), Copper(II), Zinc(II), Cadmium(II) and Dinuclear Uranyl(VI) Complexes with N,N-bis(2-{[(2,2-dimethyl-1,3-dioxolan-4-yl)methyl]amino}butyl) N′,N′-dihydroxyethanediimidamide

“…Vic-dioximes and their coordination compounds are widely used for various purposes in analytical, pigment, biological chemistry, chemical industry, medicinal chemistry and model compounds [2][3][4][5]. In our previous studies we investigated the synthesis and characterization of various transition metal complexes of new vic-dioximes [6][7][8][9][10][11][12][13][14][15][16]. In the present paper we report the synthesis and characterization of mononuclear Co II , Ni II , Cu II , Zn II , Cd II and dinuclear UO 2 VI complexes.…”
