Synopsis: The crystal structure of the novel Al77Rh15Ru8 phase (which is an approximant of decagonal quasicrystals) was determined from automated electron diffraction tomography (ADT) data. It has one of the most complicated intermetallic structures solved solely by electron diffraction methods.
Synopsis: The electron-density distribution in Cu2O has been critically reexamined to test controversial conclusions from earlier experimental and theoretical studies.
Synopsis: Metal-metal-bonded dirhodium complexes with four chelating biimidazole ligands at equatorial sites and two axial ligands gave novel assembled structures with common inorganic anions.
Synopsis: Chain polymers crystallize from aqueous solutions of CaII and MnII halides with enantiopure or racemic alanine to form a series of closely related structure types.
Synopsis: High-resolution crystal structure determination and refinement of 1-(4'-chlorophenyl)-2-methyl-4-nitro-1H-imidazole-5-carbonitrile revealed the presence of 2.5% of its bromine derivative, which would not be found using standard resolution data (ca 0.8 Å), as disorder was visible only at high resolution.
Synopsis: Single-crystal neutron diffraction, ab initio calculations and Raman spectroscopy are applied to understand the structure and hydrogen bonding of ammonium carbonate monohydrate, a hitherto poorly characterized substance, particularly in relation to other ammonium-bearing compounds.
Synopsis: The structure of an extremely rare 1M polytype of the 1:1 layer silicate cronstedtite from Eisleben (Saxony-Anhalt, Germany) was refined against a single-crystal X-ray data set. The deformation parameters of tetrahedral and octahedral sheets, arrangement of hydrogen bonds, stacking rule and desymmetrization are presented and discussed.
Synopsis: The contrasting behaviour of N-(carboxymethyl) maleamic acid and N-carbamyl maleamic acid under cyclodehydration conditions are discussed in the light of X-ray diffraction and modelling studies.
