Structure and optical properties of a trimetallic cobalt–molybdenum–sodium metal–organic framework

The structure of a trimetallic MOF synthesized under solvothermal conditions has been determined using 3D electron diffraction with bulk sample purity assessed by Rietveld analysis of high-resolution powder X-ray diffraction. The 3D connected structure con­tains tetra­hedral Mo^VI, five-coordinate Co^II and six- and seven-coordinate Na, connected by benzene-1,3,5-tri­carboxyl­ate, and shows a UV–Vis spectrum consistent with the trigonal bipyramidal cobalt(II) centre.

Effect of counteranions on the crystal structures of Zn^II coordination polymers with 1,3-bis­(1H-imidazol-1-yl)benzene

Anionic templating plays a crucial role in determining the assembly of {[Zn(L)₂(H₂O)₂]²⁺}_n [L is 1,3-bis­(1H-imidazol-1-yl)benzene] chains into either dense or porous 3D frameworks.

Structural and biological aspects of (tert-but­oxy­carbonyl­amino)­propyl­phospho­nate derivatives

Three derivatives of (tert-but­oxy­carbonyl­amino)­propyl­phospho­nate were analyzed in terms of pharmacokinetic, structural and anti­bacterial activity.

Chiral three-dimensional cadmium(II)-based coordination polymer constructed from a lactic acid derivative: synthesis, structure and properties

In the presence of pyrazine (pyr), the self-assembly reaction of (R)-5-(1-carb­oxy­eth­oxy)isophthalic acid, (R)-H₃cia, with Cd^II ions constructed a three-dimensional framework [Cd₃{(R)-cia}₂(pyr)(H₂O)₄] (HU32-R) with SHG activity.

Salt forms of a thio­amide: protonation of 1-(2,6-di­methyl­phen­yl)thio­urea

Treating the thio­amide 1-(2,6-di­methyl­phen­yl)thio­urea (DMPT) with concentrated aqueous strong acids gave three salt forms with protonation at the thio­amide S atom. Protonation causes lengthening of the C=S bond and shortening of the C—N bonds in effects similar to those seen when amides are pro­ton­ated at the O atom.

Room-tem­per­ature crystal structures of [CH(NH₂)₂]₃Sb₂X₉ (X = Br and I)

Two new vacancy-ordered formamidinium anti­mony halide triple-per­ov­skites, FA₃Sb₂X₉ {FA = [CH(NH₂)₂]⁺; X = Br and I}, measured by single-crystal X-ray diffraction are described.
