Bond-length distributions for ions bonded to oxygen: results for the non-metals and discussion of lone-pair stereoactivity and the polymerization of PO4

Bond-length distributions are examined for three configurations of the H+ ion, sixteen configurations of the group 14–16 non-metal ions and seven configurations of the group 17 ions bonded to oxygen. Lone-pair stereoactivity for ions bonded to O2− is discussed, as well as the polymerization of the PO4 group.

Bond-length distributions for ions bonded to oxygen: results for the lanthanides and actinides and discussion of the f-block contraction

Bond-length distributions have been examined for eighty-four configurations of the lanthanide ions and twenty-two configurations of the actinide ions bonded to oxygen. The lanthanide contraction for the trivalent lanthanide ions bonded to O2− is shown to vary as a function of coordination number and to diminish in scale with increasing coordination number.

Bond-length distributions for ions bonded to oxygen: metalloids and post-transition metals

Bond-length distributions are examined for 33 configurations of the metalloid ions and 56 configurations of the post-transition-metal ions bonded to oxygen. Lone-pair stereoactivity is discussed.

Using structural mimics for accessing and exploring structural landscapes of poorly soluble molecular solids

The concept of using a structural mimic for accessing and identifying the most important solid-state structural features in target molecules that are difficult to crystallize is explored.

The crystal structure of cesbronite, Cu3TeO4(OH)4: a novel sheet tellurate topology

The novel crystal structure of cesbronite has been determined. It is composed of corrugated sheets of edge-sharing CuO6 and (Cu0.5Te0.5)O6 octahedra and shows well defined ordering of Cu and Te.

Supramolecular heterosynthon assemblies of ortho-phenyl­enedi­amine with substituted aromatic carb­oxy­lic acids

Five crystal structures obtained from co-crystallization experiments of ortho-phenyl­enedi­amine with substituted aromatic acids (phthalic acid, salicylic acid, 4-hy­droxy­benzoic acid, 4-nitro­benzoic acid and 3,5-di­nitro­benzoic acid) are reported. The formation of heterosynthons between cation and anion in the five salts is discussed.

X-ray, dielectric, piezoelectric and optical analyses of a new nonlinear optical 8-hy­droxy­quinolinium hydrogen squarate crystal

The structure of a novel nonlinear optical 8-hydroxyquinolinium hydrogen squarate single crystal and the three-dimensional expansion of its supramolecular chain are reported. Hirshfeld surface analysis shows that the 8-hy­droxy­quinolinium cation and the hydrogen squarate mono-anion are connected through O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds.
