Hydrogen- and halogen-bonding-directed trimeric supramolecular motifs in dihalogenated 1,2,4-triazoles

The presence of three unique trimeric supramolecular motifs in the crystal structures of dihalogenated 1,2,4-triazole derivatives is explored.

A comparison of the isostructural [Co(NH₃)₅NO₂]XNO₃ and [Co(NH₃)₅ONO]XNO₃, X = Cl⁻ or Br⁻ in relation to nitro–nitrito linkage isomerization and photomechanical effects

[Co(NH₃)₅NO₂]BrNO₃ and [Co(NH₃)₅ONO]BrNO₃ were crystallized and their structures solved for the first time. The structures are compared with those of previously known compounds, [Co(NH₃)₅NO₂]ClNO₃ and its nitrito form [Co(NH₃)₅ONO]ClNO₃, in which linkage photoisomerization is accompanied with a mechanical response.

Crystal structures of two new high-pressure oxynitrides with composition SnGe₄N₄O₄, from single-crystal electron diffraction

A new ternary oxynitride SnGe₄N₄O₄ has been synthesized under high-pressure high-temperature conditions in a large-volume press. Its crystal structure (P6₃mc) and the crystal structure of a 6R polytype (R3m) were determined by three-dimensional electron diffraction from submicrometre-sized crystals.

Supramolecular synthons in hydrates and solvates of lamotrigine: a tool for cocrystal design

Robustness of supramolecular synthons in the lamotrigine solvates and hydrate has been investigated in order to be applied for the lamotrigine cocrystals design.

Features of the crystal structure and surface of superprotonic conductor caesium hydrogen sulfate phosphate

The crystal structure and surface layers of superprotonic conductor caesium hydrogen sulfate phosphate have been investigated by neutron diffraction and atomic force microscopy methods. Accurate data on their hydrogen bonding and surface characteristics have been obtained.

Ultrasound-assisted synthesis of a Eu³⁺-functionalized Zn^II coordination polymer as a fluorescent dual detection probe for highly sensitive recognition of Hg^II and L-Cys

A novel dual-detection fluorescent sensing platform, Eu@nZCP, for highly selective sensing of mercury and L-cysteine in aqueous media is introduced. The platform is based on a new nanoscale Zn^II coordination polymer (nZCP) synthesized using ultrasound irradiation and incorporates Eu³⁺ ions into its host lattice (Eu@nZCP). The analog single crystal was also prepared and using single-crystal X-ray diffraction, its structure determined as a 2D porous coordination polymer with a distinctive 6³ network.
