Chelate structures of 5-(H/Br)-2-hydroxybenzaldehyde-4-allyl-thiosemicarbazones (H2L): Synthesis and structural characterizations of [Ni(L)(PPh3)] and [Ru(HL)(2)(PPh3)(2)]
Ulkuseven, Bahri; Bal-Demirci, Tuelay; Akkurt, Mehmet; Yalcin, Serife Pinar; Büyükgüngör, Orhan (Pergamon-Elsevier Science Ltd, 2008)The reactions of 5-R-2-hydroxybenzaldehyde-4-allyl-thiosemicarbazone [R: H (L-1); Br (L-2)] with {M-II(PPh3)nCl(2)] (M = Ni, n = 2 and M = Ru, n = 3) in a 1:1 molar ratio have given stable solid complexes corresponding to ... -
Hydrogen-bonded and -stacked nickel(II) thiosemicarbazone complexes: Synthesis, spectral and structural studies
Guveli, Suekriye; Özdemir, Namık; Bal-Demirci, Tuelay; Soylu, Mustafa Serkan; Ulkuseven, Bahri (Springer, 2019)Mixed ligand Ni(II) complexes were synthesized from triphenylphosphine and S-methyl- or S-ethyl-isothiosemicarbazone ligands derived from 3-bromo-5-chloro-2-hydroxy-benzaldehyde. The complexes were characterized by ... -
Nickel(II) complexes of ONS and ONN chelating thiosemicarbazones with triphenylphosphine co-ligands
Guveli, Suekriye; Bal-Demirci, Tuelay; Özdemir, Namık; Ulkuseven, Bahri (Springer, 2009)Reactions of 5-bromo-2-hydroxy-benzaldehyde-S-R-4-R-1-thiosemicarbazones, [R, R-1 = H,H (L-1); CH3, H (L-2); H, C6H5 (L-3); CH3, C6H5 (L-4)] with [Ni(PPh3)(2)Cl-2] in 1:1 molar ratio yielded complexes of general formula ... -
Quantum-chemical, spectroscopic and X-ray diffraction studies on nickel complex of 2-hydroxyacetophenone thiosemicarbazone with triphenylphospine
Guveli, Sukriye; Özdemir, Namık; Bal-Demirci, Tuelay; Ulkuseven, Bahri; Dinçer, Muharrem; Andac, Omer (Pergamon-Elsevier Science Ltd, 2010)Reaction of 2-hydroxyacetophenone thiosemicarbazone with [Ni(PPh(3))(2)Cl(2)] in optimized conditions afforded a mixed ligand complex with an isolated triphenylphosphine molecule. The structure was characterized by elemental ... -
Synthesis, spectroscopic and crystallographic characterization of the cobalt(III) ternary mixed-ligand complexes of N(4)-allyl/methyl thiosemicarbazones, N,N,N',N'-tetramethylethylenediamine and azide
Bal-Demirci, Tuelay; Akkurt, Mehmet; Yalcin, Serife Pinar; Büyükgüngör, Orhan (Springer, 2010)Mixed-ligand ternary cobalt(III) complexes consisting of N,N,N',N'-tetramethylethylenediamine (tmen), R-salicylaldehyde-N(4)-allyl/methyl thiosemicarbazones (R=3-OMe (L-I/L-II) or H (L-III/L-IV) and azide, of general formula ...
