The structures of synthesized Ir₂S₃ and Rh₂S₃ were refined using single-crystal X-ray diffraction. Crystallization of these minerals in the Earth's mantle was discussed with respect to the obtained Debye temperature.

Hexa- and octa­bromo­ferrocene, as well as a mercury derivative of deca­bromo­ferrocene, were isolated from mixtures of polybromo­ferrocenes and characterized by X-ray diffraction. The crystals show halogen and hydrogen bonding, which act co-operatively.

A novel Cd^II com­pound with a two-dimensional structure was obtained by self-assembly from 5-[(3-carb­oxy­phen­oxy)meth­yl]isophthalic acid. The structure was analyzed and the photoluminescence properties were explored. The com­pound shows a high selectivity and sensitivity for detecting Fe^III cations and Cr^VI oxyanions in aqueous solution, with a low detection limit of 0.19 µM for Fe³⁺ ions and 1.13 µM for Cr₂O₇²⁻ ions.

The crystal structure of 2,4,6-tri­methyl­pyrylium tetra­fluoro­borate reveals a significant contribution of fluorine-centred inter­actions, com­prising F⋯O, F⋯π and C—H⋯F contacts, which governs the crystal packing in the solid state. The qu­anti­tative and qualitative aspects of these contacts were also established.

Primary weak hydrogen bonds in each of three independent mol­ecules in 3,4-bis-O-propargyl-1,2:5,6-di-O-iso­propyl­idene-D-mannitol are elucidated by single-crystal X-ray diffraction and their importance in mol­ecular con­formation and crystal packing determined. Parallel searches of the Cambridge Structural Database using motifs based on donor and acceptor propargyl D—H⋯A contacts reveal distance and angle dependencies that are especially sensitive to acceptor type, so, together, these findings will be beneficial in applications for the mol­ecule and its congeners as anion binders and precursors for the synthesis of macrocycles.
