Synthesis and Crystal Structure of an Inorganic-Organic Hybrid Material: [1,1′-dibutyl-4,4′-bipyridinium][α-Mo₈O₂₆]_0.5

<div><p>A novel inorganic–organic hybrid polyoxometalate, [1,1′-dibutyl-4,4′-bipyridinium,][α-Mo₈O₂₆]_0.5 (<b>1</b>), has been synthesized by the cation-templated self-assembly with octamolybdate anions under hydrothermal reaction conditions. The structure has been determined by single-crystal X-ray diffraction analysis and further characterized by PXRD, IR spectra, and elemental analysis. The crystal data analysis revealed that the compound was composed of one discrete [1,1′-dibutyl-4′-bipyridinium]²⁺ cation and 0.5 polyacid anions [Mo₈O₂₆]^4– interacted by electrostatic interactions. In the compound the anion fraction take on a [α-Mo₈O₂₆]^4– cluster.</p></div

Syntheses and Crystal Structure of Three Novel Supramolecular Halides/Pseudohalides {(DMB)[Cu₂(SCN)₄]}_n,{(DMB)[Cu(SCN)₄]}, and {(DMB)[Ag₂(SCN)₄]}_n Directed by Dicationic Template Possessing C2-Symmetry

<div><p>Three novel hybrid complexes, namely{(DMB)[Cu₂(SCN)₄]}_n (<b>1</b>), {(DMB)[Cu(SCN)₄]} (<b>2</b>), <b>and</b> {(DMB)[Ag₂(SCN)₄]}_n (<b>3</b>), have been synthesized via the self-assembly in DMF–methanol system based on multidentate ligand DMB, {DMB = α, α<i>′</i>- di(3-methylimidozole-1-yl)benzene dichloride}. Single-crystal X-ray diffraction analysis shows <b>1</b> and <b>3</b> are 1D supramolecules, whereas <b>2</b> is mononuclear. Electrostatic interactions between the organic counteranions and inorganic moieties are present and do the contribution to the crystal packing. These compounds have been further characterized by IR spectroscopy and thermostability properties.</p></div
