The electronic structures of dinuclear copper complexes of the general formula [GFA(CuX2)2], where X = Br or Cl and GFA denotes a redox-active bridging Guanidino-Functionalized Aromatic ligand, were analysed and compared. The diamagnetic complexes [GFA(CuBr2)2] can all be described as dinuclear CuI complexes with bridging GFA2+ dicationic ligand units exhibiting a [CuI-GFA2+-CuI] electronic str...

Platinum bis-amidine complexes (both the cis and trans isomers) are stable in acetone and chlorinated solvents but are unstable in protic solvents such as methanol or water. In the latter solvents an initial cis/trans isomerization leads to formation of an equilibrium mixture with a cis/trans ratio of about 1:4; subsequently a dinuclear platinum(III) complex (1) is formed under aerobic conditio...

A new dinuclear copper complex and several Cu-amino acid complexes inhibit protein tyrosine phosphatase 1B competitively at submicromolar levels, suggesting that copper complexes may interfere with cellular signaling pathways by inhibiting protein tyrosine phosphatases.

Dinuclear carboxylate-bridged zinc complexes of one symmetric and one asymmetric phenolate-based ligand catalyse the transesterification of 2-hydroxypropyl-p-nitrophenyl phosphate (HPNP) at different rates, with an unsymmetrical complex being more active than a symmetric one.

Using a family of novel mononuclear and dinuclear palladium complexes of phanephos ligands, the simultaneous control of regioselectivity and enantioselectivity in the hydroxycarbonylation and alkoxycarbonylation of styrene derivatives has been realised for the first time.

A dinuclear ruthenium catalyst with a rigid anthracene spacer shows excellent regio- and stereo-selectivity in the atom-economic addition of aliphatic carboxylic acids to phenylacetylene, producing exclusively anti-Markovnikov enol-esters with high E/Z ratios of the isomers.

The synthesis and structure of rare acyclic alkoxy- and aminocarbene complexes of gold(i) are reported, including a novel ferrocenophane dinuclear biscarbene complex. X-Ray diffraction analyses and DFT calculations reveal that these complexes are stabilized by genuine aurophilic interactions.

Asymmetric hydrogenation of quinazolinium salts was catalysed by halogen-bridged dinuclear iridium complexes bearing chiral diphosphine ligands, yielding tetrahydroquinazoline and 3,4-dihydroquinazoline with high enantioselectivity. A derivative of chiral dihydroquinazoline was used as a chiral NHC ligand.

The unsymmetrical dinucleating ligand 2-(N-isopropyl-N-((2-pyridyl)methyl)aminomethyl)-6-(N-(carboxylmethyl)-N-((2-pyridyl)methyl)aminomethyl)-4-methylphenol (IPCPMP or L) has been synthesized to model the active site environment of dinuclear metallohydrolases. It has been isolated as the hexafluorophosphate salt H(4)IPCPMP(PF(6))(2) x 2 H(2)O (H(4)L), which has been structurally characterized,...

Six Mn(II) coordination compounds with tetrazolate-5-carboxylate (tzc), have been synthesized and characterized. They are of the formula [Mn2(tzc)2(H2O)2].4H2O (), Mn(tzc)(H2O)2 (), [Mn2(tzc)2(phen)2(H2O)2] (), [Mn(tzc)(2,2'-bpy)(H2O)2] (), [Mn(tzc)(4,4'-bpy)] () and [Mn2(tzc)2(H2O)2].(bpp) (), where phen=1,10-phenanthroline, 2,2'-bpy=2,2'-bipyridyl, 4,4'-bpy=4,4'-bipyridyl, and bpp=1,3-di(4-py...
