Electron states of the benzene...HCl complex have been studied by UV photoelectron spectroscopy. Two vertical ionization energies of the complex at 10.84 and 12.10 eV have been assigned to π C6H6 and nCl orbitals, respectively. While the π C6H6 orbital in the complex is shifted by 1.57 eV to higher binding energy, the nCl MO is shifted by 0.63 eV to lower binding energy with reference to the corresponding free benzene and HCl molecules. Ab initio MO calculations confirm these assignments. The toluene...HCl complex has also been studied. The larger shifts in the π(1.90 eV) and nCl(0.88 eV) orbital energies in the toluene ...HCl complex compared to those of the benzene…HCl complex are consistent with stronger π hydrogen bonding in the case of toluene.

A new class of layered alkali metal-MoO3 bronzes,AxMoO3 (A =Li, Na, K, Rb), with nearly the same unit cell parameters as the host oxide has been synthesized by the solid-state reaction of MoO3 with alkali metal iodides around 575 K; Li x MoO3 absorbs H2O causing an increase in theb parameter of the unit cell. Hexagonal potassium bronzes of W1−x Mo x O3 are synthesized for the first time.

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.

57Fe Mössbauer studies of three inorganic glasses through their glass transition temperatures, Tg, show that the Lamb-Mössbauer factor (recoil-free fraction) decreases with temperature, particularly around Tg. An attempt is made to explain the results employing the cluster model which suggests that soft modes may be associated with the glass transition.

A reentrant transition from an incipient charge-ordered (CO) state to a charge-delocalized ferromagnetic (CDFM) state has been established in the manganate ${\mathrm{Nd}}_{0.25}{\mathrm{La}}_{0.25}{\mathrm{Ca}}_{0.5}{\mathrm{MnO}}_{3},$ in which the average $A$-site ionic radius is 1.19 \AA{}. The reentrant CDFM phase is associated with a first-order phase transition that reduces the orthorhombic distortion of the lattice, in contrast to the CO transition in other manganates where the orthorhombically distorted CO state is stabilized at low temperatures. At the CO-CDFM transition, there is a collapse of the charge-ordering gap as measured by vacuum tunneling spectroscopy.

MgO nanowires and related nanostructures have been prepared by carbon-assisted synthesis, starting from polycrystalline MgO or Mg without the use of metal catalysts. The study has been carried out with different sources of carbon, all of them yielding the nanostructures with some differences. It has been possible to obtain nanotrees and other interesting nanostructures by this method. It has also been possible to obtain aligned MgO nanowires by carbon-assisted synthesis over Au-coated Si substrates. A vapor–solid mechanism of one-dimensional growth seems to be operative in the reactions carried out in bulk, but a vapor–liquid–solid mechanism applies when Si substrates are used.

Chemical shifts, ΔE, of the K-absorption discontinuity in several compounds of copper possessing formal oxidation states between 0 and III have been measured. The shifts show a parabolic dependence on the formal oxidation state as well as on the effective atomic charge, q, on copper. Anomalous chemical shifts shown by some of the compounds are discussed in terms of the bonding in these compounds. The ΔE values have also been correlated with the core electron binding energies obtained from X-ray photoelectron spectroscopy.

Iron nanowires encapsulated in aligned carbon nanotube bundles show interesting magnetic properties. Besides the increased coercivity, Barkhausen jumps with 5 emu/g steps in magnetization are observed due to magnetization reversal or depinning of domains.
