Synopsis: The crystal structure of the new mineral FeCrO3 has been determined. The studied single crystal is found to belong to space group and the structure refinement evidences an ordered cation distribution, consistent with the ilmenite structural type.
Synopsis: Peculiarities of intra- and intermolecular bonding and magnetic properties of bis(chloro-(2-5-(1-(hydroxyimino)ethyl)pyrazol-1-ide)-pyridine-copper(II)) were investigated.
Synopsis: This paper describes how the crystalline state photochromic properties changed depending on the bond flexibility and size of the alkyl groups at the nonaromatic alkylidene moiety of 3-furylfugides. Results obtained revealed clearly that fulgide with a big and flexible alkylidene group showed much better photochromic properties due to more space available around the reactive area and bond flexibility which can reduce the strain built up in the C-isomer and nearby lattice by obtaining different conformations .
Synopsis: We show by a combination of diffraction and spectroscopic methods that CuH produced by borohydride reduction of a CuII salt consists of a core of CuH with the Wurtzite structure and a shell of water. We also demonstrate that the shell is exchangeable for ethanol.
Synopsis: novel compound Cs2CuAl4O8 was synthesized from a phosphate flux and its structure was determined from single-crystal X-ray diffraction data; topological relations with zeolite-like phases are discussed. The quantum ground state of this compound is gapped spin liquid.
Synopsis: The crystal structure of two new natural Bi oxysulfates with the formula Bi14O16(SO4)5 and Bi30O33(SO4)9(AsO4)2 from the high-temperature fumarole deposit of the La Fossa crater at Vulcano (Aeolian Islands, Italy) has been solved and refined from X-ray single-crystal diffraction data. Both the structures can be properly described in terms of oxo-centered OBi4 tetrahedra.
Synopsis: The incommensurate modulated crystal structure of Sr3B2 + xSi1 - xO8 - x/2 solid solutions in the Sr3B2SiO8-Sr2B2O5 section are described in (3 + 2)-dimensional space. Orientation preferences of the BO3 units lead to a strong anisotropy of thermal expansion.
