Ruthenium(II) complexes with phenanthroline-, benzimidazole-, benzothiazole-, and pyridine-derived bidentate and tridentate ligands: reactivity and spectroscopic and electrochemical characterization
Springer Science and Business Media LLC - Tập 18 - Trang 197-204 - 1993
Michael R. McDevitt, Yu Ru, Anthony W. Addison
Ruthenium complexes of some tridentate and bidentate benzimidazole-, benzothiazole- and pyridine-derived ligands have been prepared as their PF f6 p− salts, and their constitutions have been confirmed by elemental analysis, 1H-n.m.r. spectroscopy and electrochemistry. The complexes are redox-active, displaying a metal-centred RuII/ RuIII oxidati...... hiện toàn bộ
Synthesis and characterization of heterobimetallic mixed-ligand complexes containing Zr(μ-OPri)2Al bridging units

A new inorganic–organic hybrid compound constructed from polyoxoanions and rare earth coordination complexes
Springer Science and Business Media LLC - Tập 31 - Trang 770-775 - 2006
Juan Li, Xihe Yu, Hongfang Wang, Kun Xu, Xinyu Wu, Lei Hou, Jing Li
A new chainlike polymer, Na[Ce(dipic)(H2O)3]2 [CrMo6H6O24] · 13H2O (H2dipic = pyridine-2,6-dicarboxylic acid) (1), has been synthesized and characterized by elemental analysis; IR and XPS spectroscopy, TG analysis, and single-crystal X-ray diffraction. Compound (1) is built up of Anderon-type polyoxoanions as structural motifs and cerium–dipic coordination fragments as linkers to yield an unpreced...... hiện toàn bộ
Synthesis and characterization of cobalt(II) and copper(II) complexes with 5-amino-3,4-dimethylisoxazole
Springer Science and Business Media LLC - Tập 2 - Trang 5-9 - 1977
Marco Biddau, Marcella Massacesi, Rosalba Pinna, Gustavo Ponticelli
Complexes of cobalt(II) and copper(II) with 5-amino-3,4-dimethylisoxazole (5-ADI) have been prepared and studied by means of magnetic susceptibility measurements, near and far i.r. spectra, electronic spectroscopy and, when possible, conductivity measurements. The 5-ADI generally behaves as bridging (Nring-, O- or Nring-, -NH2) ligand. All the complexes have an octahedral sterochemistry, except Co...... hiện toàn bộ
Antioxidative and anti-tumour activities of solid quercetin metal(II) complexes
Springer Science and Business Media LLC - Tập 26 - Trang 57-63 - 2001
Jing Zhou, Liufang Wang, Jinyi Wang, Ning Tang
Six metal(II) complexes with quercetin ML2 · nH2O [L = quercetin (3-OH group deprotonated); M = Mn, Co, Ni, Cu, Zn, and Pb; n = 2 or 3] have been prepared and characterized by elemental analysis, complexometric titration, thermal analysis, conductivity, i.r., u.v., 1H-n.m.r. and fluorescence spectral techniques as well as by cyclic voltammetry. The antioxidative and anti-tumour activities of querc...... hiện toàn bộ
Low-dimensional compounds containing cyano groups. III: a structural, spectral and thermal study of dicyanoargentates containing 4-methylpyridine
Springer Science and Business Media LLC - Tập 28 - Trang 808-815 - 2003
L'ubica Triščíková, Ivan Potočňák, Jozef Chomič
The complexes CuII(4-Mepy)2Ag2(CN)4 (1) and CuII(4-Mepy)3Ag2−x CuI x (CN)4 (2) (4-Mepy = 4-methylpyridine, x = 0.07) were isolated from a reaction mixture containing 4-Mepy, K[Ag(CN)2] and CuSO4. I.r. spectra indicated the presence of both monodentate and bridging cyano groups in (1) and (2), confirmed by their known structures, both consisting of neutral zigzag ...... hiện toàn bộ
New vic-dioxime transition metal complexes
Springer Science and Business Media LLC - Tập 26 - Trang 300-306 - 2001
Selahattin Serin
New vic-dioxime ligands and their CuII, CoIII, NiII and VOIV complexes have been prepared and characterized by elemental analyses, i.r. and u.v. spectra, magnetic moments and molar conductance data. The CoIII complexes are diamagnetic. The 1H- and 13C-n.m.r. and g.c./m.s. spectra of the vic-dioxime ligands and their CoIII complexes were recorded. The compounds are all non-electrolytes.
Synthesis of air-stable mixed bis-carboxylate titanocene complexes and their catalytic behaviors in cross-aldol and Mannich reactions
Springer Science and Business Media LLC - Tập 41 - Trang 731-738 - 2016
Jing Wang, Xi Chen, Xiu Wang, Wei-Qiang Zhang, Hua-Ming Sun, Guo-Fang Zhang, Ya Wu, Zi-Wei Gao
Tunable organometallic Lewis acid catalysts were developed by combining salicylic acid (H2-Sal) with benzoic acid (H-Ben), 4-fluorobenzoic acid (H-BenF) and 3-thiophenic acid (H-Th), as coligands for mixed bis-carboxylate titanocene complexes. Three air-stable complexes [Cp2Ti(η1-HSal)(η1-Ben)] (1), [Cp2Ti(η1-HSal)(η1-BenF)] (2) and [Cp2Ti[η1-HSal][(η1-Th)] (3) were prepared in high yields by the...... hiện toàn bộ
