Synopsis: C-(A)-S-H(I) is a structurally imperfect form of 14 Å tobermorite that is studied extensively as a model for the main binding in concrete. Crystal-chemically plausible structures are developed that account for a wide range of experimental observations, including variations in calcium to silicon ratio, water to silicon ratio, (alumino)silicate anion structure and layer spacing.
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: 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.
