Acid dissociation kinetics of the copper(II) Ccomplex of 1,5,8,12-tetra-azacyclo-octadecane ([18]aneN4) and the nickel(II) complex of 1,5,8,12-tetra-azacycloheptadecane ([17]aneN4)
Springer Science and Business Media LLC - Tập 11 - Trang 261-264 - 1986
Robert W. Hay, Mahesh P. Pujari, Ramesh Bembi
The kinetics of the dissociation of [Cu([18]aneN49)]2+ and [Ni([17]aneN48)]2+ in acidic solution have been studied in detail. The dissociation of [Cu([18]aneN48)]2+ displays saturation kinetics beyond 0.4 mol dm−3 HC1O4 with values of kobs becoming independent of [HClO4]. The kinetic behaviour can be rationalised in terms of the scheme, ...... hiện toàn bộ
Ligating properties oftert-phosphine/arsine sulphides or selenides, Part IX. Preparation and spectroscopic studies of copper(I)/copper(II) complexes with bis(—phosphine chalcogenides)
Springer Science and Business Media LLC - Tập 16 - Trang 57-59 - 1991
Tarlok S. Lobana
The analytical, molar conductance and spectroscopic studies of new complexes of copper(I) and copper(II) with bis(—phosphine chalcogenides), Ph2P(E)(CH2)n-P(E)Ph2(L-L) are reported. The complexes are of the types: (a) [CuX(L-L)](X, n, E: Cl, 2–4, Br, 2, S; Cl, Br, 1, Se); (b) [Cu2X2(L-L)] (X, n, E: Cl, Br, 2, 3, Se) and (c) [CuCl2(L-L)] (n, E: 2, 3, S). Possible structures have been derived.
Synthesis, protonation and substitution behaviour of K3[ReO2(CN)4]
Springer Science and Business Media LLC - Tập 12 - Trang 209-212 - 1987
Johann G. Leipoldt, Stephen S. Basson, Andreas Roodt, Walter Purcell
The preparation and characterization of salts of the [ReO2(CN)4]3−, [ReO(OH)(CN)4]2−, [ReO(H2O)(CN)4]−, [Re2O3(CN)8]4− and [ReO(NCS)(CN)4]2− species are described. The nature of the protonation reactions of [ReO2(CN)4]3− was established by the successful isolation of these salts.
Two manganese(II) complexes based on anthracene-9-carboxylate: Syntheses, crystal structures, and magnetic properties
Springer Science and Business Media LLC - Tập 34 - Trang 51-60 - 2008
Chun-Sen Liu, E. Carolina Sañudo, Li-Fen Yan, Ze Chang, Jun-Jie Wang, Tong-Liang Hu
To explore the influence of the anthracene ring skeleton, with a large conjugated π-system, on the structures and properties of its complexes, two MnII complexes with anthracene-9-carboxylate ligand were synthesized and structurally characterized: {[Mn(L)2(H2O)2](H2O)}∞ (1) and [Mn2(L)4(phen)2(μ-H2O)](CH3OH) (2) (L = anthracene-9-carboxylate and phen = 1,10-phenanthroline). Complex (1) has a one-d...... hiện toàn bộ
Synthesis of new dinuclear dicopper(II) and dinickel(II) complexes. The kinetics of catechol oxidase and electrochemistry of a dicopper(II) complex
Springer Science and Business Media LLC - Tập 30 - Trang 128-135 - 2005
Farukh Arjmand, Shamima Parveen, Sartaj Tabassum
A new dinuclear ligand L′, ethylene[OO′-bis-salicylidene-β-diketone] bearing two symmetrical coordination sites was synthesized by the condensation of salicylaldehyde and acetylacetone, L, with 1,2-dibromoethane under reflux. The ligand L′ in a 1:1 ratio was treated with CuCl2 and NiCl2 to yield the complexes, tetrachloro bis[OO′-bis- salicylidene-β-diketone copper(II)] and bis[OO′-bis-salicyliden...... hiện toàn bộ
Novel dioximato-bridged chromium(III)-copper(II)-chromium(III) trinuclear complexes with ferromagnetic exchange interactions

Si-Wei Zhang, Dai-Zheng Liao, Zong-Hui Jiang, Geng-Lin Wang
Two new dioximato-bridged trinuclear CrII-CuII-CrIII complexes, [Cr(salen)-Cu(α-BD)2-Cr(salen)] (1) and [Cr(salen)-Cu(α-FD)2-Cr(salen)]-H2O (2), have been prepared and characterized [salen2− = N,N′-ethylene- bis (salicylideneiminate), (α-BD)2− = α-benzyldioximato and (α-FD)2− = α-furildioximato]. Magnetic susceptibility measurements in the 4.2–300 K range demonstrated the operation of a ferromagne...... hiện toàn bộ
Synthesis, Characterization, Electrochemical Properties and Antibacterial Activity of Some Transiton Metal Complexes with [(2-hydroxy-1-naphthaldehyde)-3-isatin]-bishydrazone
Springer Science and Business Media LLC - Tập 31 - Trang 441-446 - 2006
Balakrishnan Murukan, Kochukittan Mohanan
A bishydrazone was prepared by reacting isatin monohydrazone with 2-hydroxy-1-naphthaldehyde and a series of metal complexes with this new ligand were synthesised by reaction with MnII, FeII, CoII, NiII, CuII and ZnII salts. The complexes were characterised on the basis of elemental analysis, molar conductance, magnetic susceptibility data, u.v.–visible, i.r., e.s.r. and n.m.r. spectral studies, w...... hiện toàn bộ
