The simple mixing of Ag+ and VO2+ in water, at room temperature, results in the very efficient synthesis of silver nanodendrites in the absence of any template or surfactant. The same procedure proved successful for the synthesis of Pd nanodendrites.

Crystals of a novel type of BEDT-TTF salt, [BEDT-TTF]2[Cu2Br3], were obtained by the BEDT-TTF electro-oxidation with the electrolyte molar ratio [Ph4P][N(CN)2]:CuBr of 1:8 in a mixture of THF and ethyleneglycol, whereas crystals of κ-[(BEDT-TTF)2][Cu(N(CN)2)Br] were formed with the electrolyte molar ratio [Ph4P][N(CN)2]:CuBr of 1:1.

Two anthracene fragments were added to the edges of a linear dioxotetramine ligand in order to exploit photocyclization and obtain a photoswitchable selective receptor for CuII, with a cavity that can be closed on command. The new ligand can also be used for the photorelease of protons in aqueous solution, as a result of photoinduced pKa modulation.

Article first published online: 31 JAN 2011 | DOI: 10.1002/ejic.201001157
We synthesized a novel compound, namely a liquid crystalline iron(III) Schiff base complex with the asymmetric ligand [Fe(L)X(H2O)2]+X–, where X = PF6– is the counterion. This compound has a labilelow-spin electron configuration that switches between the (dxz,dyz)4(dxy)1/(dxy)2(dxz,dyz)3 ground states and is temperature-dependent.

Article first published online: 28 JAN 2011 | DOI: 10.1002/ejic.201001170
The stereoelectronic features of the phosphacycle ligand shown in the graphic [n = 1, Z = S (1); n = 1, Z = Se (2); n = 1, Z = Fe(CO)4 (3); n = 1, Z = W(CO)5 (4); n = 2, Z = trans-Rh(CO)Cl (5)] have been assessed through synthesis and characterisation of a number of relevant derivatives. The empirical data support the classification of the ligand as a bulkier analogue of PPh3.

Triazine Ligands

Article first published online: 27 JAN 2011 | DOI: 10.1002/ejic.201001104
A new triazine-based ligand (L) features threefold symmetry and three potentially tridentate {N3} binding pockets, but binds only a single MnII by using one of the triazine N atoms and two of its chelate arms. Using azide as an additional ligand, the {LMnII} building blocks can form mononuclear, binuclear, and 1D chain structures with heptacoordinate metal ions.

Article first published online: 21 JAN 2011 | DOI: 10.1002/ejic.201001139
A new series of ligands with an AB2 structure were synthesized and employed in Fe2+ SCO complexes. ΔH, ΔS and T1/2 for the SCO were determined using Evans' method. The results clearly show a dependency of the spin state on the substitution pattern. The steric effects of substituents placed at the 6 and 6′ positions in the biphenyl moiety are effectively transported through the biphenyl bridge.

Article first published online: 26 JAN 2011 | DOI: 10.1002/ejic.201001164
Metal cation dependent modulation of the photophysical properties of a platinum(II) complex featuring a dipicolylanilino–acetylide ligand is described. The ground-state absorption and excited-state luminescenceof the complex are modulated by binding of divalent metal ions; the extent of the observed changes was found to be dependent upon the identity of the metal ion.

Chiral-at-metal ruthenium chloro indenyl phosphoramidite complexes have been converted into the corresponding allenylidene complexes, some of which have been structurally characterized. The chiral information was transferred from the chloro precursor complexes to the allenylidene complexes, which were obtained as optically pure diastereomers. Only one diastereomer was formed during the syntheses.

Article first published online: 2 FEB 2011 | DOI: 10.1002/ejic.201001251
[VO(acac)2] or [VO(OPr)3] reacts with aminoethanol bis(phenol)s to form [VOL1]-type complexes, which are monomers or dimers in the solid state but monomers in solutions. In wet polar solvents [VOL1] (1) undergoes an N-alkyl elimination to form 3,5-dimethylsalicyl alcohol, which reacts further with 1 and the condensation product [VOLC1] can be isolated. A similar condensation product [VOLC2] is formed when 1 is heated in dry acetonitrile with salicyl alcohol.

New zinc-based metal–organic frameworks (MOFs), binary zinc carboxylates ZnCnCn′ with Cn and Cn′ = CH3(CH2)n – 2COO–, have been synthesised and characterised for anti-corrosion applications on zinc. The crystallographic structures demonstrate the great flexibility of these MOFs in modifying the insolubility and hydrophobicity of the protective coatings on metals in an aqueous solvent process.
