cis-Chloridobis(4,4′-dimethyl-2,2′-bipyridine)nitrosylruthenium(II) bis(hexafluorophosphate)

In the cation of the title complex, [RuCl(NO)(C12H12N2)2](PF6)2, the central RuII ion is sixfold coordinated by a chloride ion and a nitrosyl ligand, which are cis to one another, and by four N atoms of two 4,4′-dimethyl-2,2′-bipyridine ligands, in a slightly distorted octahedral geometry. One of the PF6 − anions is located in a general position, while the other is composed of two half PF6 − anions located on twofold rotation axes. The crystal packing is dominated by C—H...F hydrogen bonds, leading to the formation of a three-dimensional supramolecular structure. There are also C—H...Cl hydrogen bonds present.

Supramolecular organization of perfluorinated 1H-indazoles in the solid state using X-ray crystallography, SSNMR and sensitive (VCD) and non sensitive (MIR, FIR and Raman) to chirality vibrational spectroscopies

The determination of the AC of three perfluorinated 1H-indazoles that resolve spontaneously as conglomerates.

The role of water in the synthesis of indium nanoparticles

We report the water-assisted synthesis of indium nanoparticles (In NPs). We found that a precise amount of water was necessary to allow the formation of the desired 7 nm In NPs: the oxidation of the In surface by water inhibits the growth of NPs as well as subsequent reactivity with white phosphorus (P₄). A novel surface activation method based on the use of organosilanes is presented.

α-CC agostic structures and aggregation diversity in cyclopropyllithium derivatives

In the presence of thf or tmeda and depending on experimental conditions, 1-phenylcyclopropyllithium may be crystallised as either dinuclear or tetranuclear species both exhibiting α-CC agostic distortions towards tricoordinate lithium cations. In thf solution, deaggregation of the dinuclear complex takes place to yield a well-defined mononuclear species [Li(thf)3(c-CPhC2H4)].

Relaxation Dynamics and Magnetic Anisotropy in a Low-Symmetry Dy(III) Complex

The magnetic behaviour of a Dy(LH)3 complex (LH(-) is the anion of 2-hydroxy-N'-[(E)-(2-hydroxy-3-methoxyphenyl)methylidene]benzhydrazide) was analysed in depth from both theoretical and experimental points of view. Cantilever torque magnetometry indicated that the complex has Ising-type anisotropy, and provided two possible directions for the easy axis of anisotropy due to the presence of two magnetically non-equivalent molecules in the crystal. Ab initio calculations confirmed the strong Ising-type anisotropy and disentangled the two possible orientations. The computed results obtained by using ab initio calculations were then used to rationalise the composite dynamic behaviour observed for both pure Dy(III) phase and Y(III) diluted phase, which showed two different relaxation channels in zero and non-zero static magnetic fields. In particular, we showed that the relaxation behaviour at the higher temperature range can be correctly reproduced by using a master matrix approach, which suggests that Orbach relaxation is occurring through a second excited doublet.
