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

Six cation-templated halometal complexes and C–H activation of alkylene-bridged azoles

<div><p>Six dication-templated complexes were discovered in efforts to investigate the effect of linear imidazolium-based template, 1,<i>ω</i>-bis(3,3′-methylimidazolium)alkyl dibromide, on pure inorganic halometal clusters. Complexes {[C₄(Mim)₂](Pb₂I₆)}_<i>n</i> (<b>1</b>) (<i>ω</i> = 4), {[C₁(Mim)₂] (Ag₂I₄)}_<i>n</i> (<b>2</b>) (<i>ω</i> = 1), {[C₃(Mim)₂](Ag₂I₄)}_<i>n</i> (<b>3</b>) (<i>ω</i> = 3), and {[C₄(Mim)₂](Ag₂I₄)}_<i>n</i> (<b>4</b>) (<i>ω</i> = 4) possess 1-D chain architecture with different organic cations trapped in it. Compound {[C₃′(Mim)₂](CuBr₃)} (<b>5</b>) (<i>ω</i> = 3) contains the mononuclear anion (CuBr₃)²⁻ and intra-molecular coupled organic cation with the formed seven-membered ring. {[C₂(Mim)₂S₂]₂(Cu₂I₂)}_<i>n</i> (<b>6</b>) (<i>ω</i> = 2) presents an infinite 2-D coordination polymer as the first representative polyrotaxane example featuring the biimidazolium thiolate cation ligand. All compounds were further characterized with IR spectra and thermal analysis properties.</p></div
