A series of dinuclear Pt(II) complexes of the type [Pt2(N,N,N',N'-tetrakis(2-pyridylmethyl)diamine(H2O)2]4+ were synthesized. Acid-base titrations, and concentration and temperature dependent stopped-flow measurements of the reaction with chloride were performed to study the thermodynamic and kinetic behaviour of the dinuclear bridged complexes. The results indicate that there is a clear intera...

The first reversible interconversion process between a one-strand polymeric copper(II) complex {[Cu2(L1)2(ClO4)2](ClO4)2}n (1) and a dicopper(II) helicate [Cu2(L1-2H)2] (2), proceeding via a deprotonation-protonation process, can transduce fluorescence and function as a fluorescent switch simply by introducing a one fiftieth equivalent of coumarine 343 anion, a fluorophore.

Ibuprofen a non-steroidal anti-inflammatory drug (NSAID) is among the most prescribed drug on the world. Copper(II) complexes with NSAIDs are more active than their parent drugs and exhibit a lower toxicity than inorganic forms of copper [1] . Further, many of these complexes, including that of copper ibuprofenate complex, have a better anti-ulcer protective effect than the parent drugs. Binary...

Copper(II) complexes, containing aliphatic tripodal tetramine ligand, [Cu(trpn)(NH3)] 2+ (1), [Cu(tren)(NH3)] 2+ (2), [Cu(332)(NH3)] 2+ (3) and [Cu(322)(NH3)] 2+ (4) are optimized at B3LYP/ LANL2DZ and B3LYP/GEN levels of theory in gas phase (where (trpn), (tren), (332) and (322) are N(CH2CH2CH2NH2)3, N(CH2CH2NH2)3, N[(CH2CH2CH2NH2)2(CH2CH2NH2)] and N[(CH2CH2CH2NH2)(CH2CH2NH2)2], respectively)....

Complexes of N-heterocyclic carbenes (NHCs) with copper(II) halogenides are unstable. Upon formation, these complexes decompose to give haloamidinium salts. Contrastingly, O-substituted copper(II) NHC complexes are fairly stable. A series of new five-, six- and seven-membered ring NHC complexes of Cu(OAc)(2) have been synthesised and characterised in the solid state.

Several novel mononuclear Zn(II) complexes, [Zn(bpy)L2], where bpy=2,2’-bipyridine and L=monoanions of phenylcyanamide (pcyd), 4-methylphenylcyanamide (4-Mepcyd), 3,5-dimethylphenylcyanamide(3,5-Me2pcyd),4-methoxyphenylcyanamide(4-MeOpcyd), 3,5-dimeth-oxyphenylcyanamide (3,5-MeO2pcyd), 3-chlorophenylcyanamide (3-Clpcyd), 2,3-dichlo...

We report the synthesis and comprehensive characterization of a series (oligo)thiophene-bridged (bis)phenanthroline ligands. The complexation behavior ditopic ligands with Cu(I) was explored by high-resolution ESI mass spectrometry, UV-vis spectroscopy, electrochemistry. Whereas ligands, in which phenanthrolines are bridged smaller (oligo)thiophene units, provided mainly mononuclear complexes, ...

The first use of methyl 2-pyridyl ketone oxime (mpkoH) in zinc(II)/lanthanide(III) chemistry leads to the [ZnLn(mpko)3(mpkoH)3](ClO4)2 and [ZnLn(NO3)2(mpko)3(mpkoH)] families of dinuclear Zn(II)Ln(III) complexes displaying blue-green, ligand-based photoluminescence; the Zn(II)Dy(III) compound shows field-induced relaxation of magnetization.

Oxidation of Au(I) in the presence of Fe(II) allowed for the synthesis of unique dinuclear ferrocenyl Au(II) complexes via the first reported enantiopure planar chiral ferrocenyl Au(I) complex. (Spectro)electrochemical studies show that oxidation at Fe(II) is favoured, but DFT studies suggest that the energy differences for oxidation of one or the other metal should be quite small.
