Abstract
The synthesis of sandwich-shaped multinuclear silver complexes with planar penta- and tetranuclear wheel-shaped silver units and a central anion, [Agn(2-HPB)2(A-)](OTf-)n-1, nAgA, n = 4 or 5 and A- = OH- or F- or Cl-, is reported, along with complete spectroscopic and structural characterization. An NMR mechanistic study reveals that silver complexes were formed in the following order: 2Ag → 3AgH2O → 5AgOH → 4AgOH. The central hydroxides in 4AgOH and 5AgOH exhibit exotic physical properties due to the confined environment inside the complex. The size of these silver wheels can be tuned by changing the central anion or extracting/adding one silver atom. This study provides the facile way to synthesize discrete wheel-shaped multinuclear silver complexes and provides valuable insights into the dynamics of the self-assembly process.

Abstract
![]()
Self-assembly of AgOTf and AgF with
the hexatopic ligands hexakis(pyridin-2-yl)benzene (2) and 2,4,6-tris(pyridin-2-yl)-1,3,5-tris(quinolin-2-yl)benzene (3) affords the discrete sandwich-shaped complexes [Ag4F(2)2](OTf)3, [Ag4F(3)2](OTf)3, and [Ag5F(2)2](OTf)4. The solid-state
structures of the complexes were characterized by single-crystal X-ray
diffraction analysis, which revealed that the fluoride anion is coordinated
in the center of the Ag4-square or Ag5-pentagon
units which are positioned between two molecules of the hexakis(azaheteroaryl)benzene.
The generation of complexes is dictated by a unique cooperation of
ligand coordination, argentophilicity, and fluoride anion inclusion.
All three complexes adopt highly symmetrical structures in solution,
as evidenced by appearance of one set of proton resonances for the
two ligands arranged face to face. Multinuclear
sandwich-shaped silver(I) complexes are readily assembled by a unique
cooperation of nitrogen-coordinating hexaheteroarylbenzene ligands,
silver atoms, and fluoride anion.

Metallosupramolecular Compounds Based on Copper(II/I) Chloride and Two Bis-Tetrazole Organosulfur Ligands. CHEMISTRY 2020.

Abstract
The present work assesses the ability of two flexible bis-tetrazole organosulfur ligands to build up different metallosupramolecular compounds based on the analysis of the different supramolecular interactions. The reaction of copper(II) chloride dihydrate with the N,N’-donor dithioether ligands bis(1-methyl-1H-tetrazole-5-ylthio)methane (BMTTM) and 1,2-bis(1-methyl-1H-tetrazole-5-ylthio)ethane (BMTTE) was investigated using different synthetic methods. Four compounds have been obtained as single crystals: two pseudopolymorphic 1D Cu(II) coordination polymers with the ligand BMTTM, a 2D Cu(II) coordination polymer and a discrete Cu(I) tetramer with the BMTTE ligand. The effects of the weak interactions on the crystal packing and the Hirshfeld surfaces of the structures were analyzed to clarify the nature of the intermolecular interactions.
