Two neutral silver(I)-phenylethynide clusters incorporating the [((t)BuPO(3))( 4)V(4)O(8)](4-) unit as an integral shell component have been isolated and characterized by X-ray crystallography. Expand
High-Nuclearity Silver Thiolate Clusters Constructed with Phosphonates.
The n-butylphosphonate ligand has been employed to construct three new silver(I) thiolate compounds. Single-crystal X-ray analysis revealed that complexes 1 and 2 are Ag48 and Ag51 coordination chainExpand
Structure-Directing Role of Phosphonate in the Synthesis of High-Nuclearity Silver(I) Sulfide-Ethynide-Thiolate Clusters.
Phosphonate ligands as structure-directing components have been employed to construct four new high-nuclearity silver(I) sulfide-ethynide-thiolate clusters, in which silver(I) aggregates tBuC≡C⊃Ag3,Expand
A pyrovanadate-templated silver(I)-ethynide cluster circumscribed by macrocyclic polyoxovanadate(V).
In the giant mixed-metal silver(I)-ethynide cluster compound, the cyclic polyoxovanadate located at a 4 site takes a contorted configuration to wrap around an inner Ag(44) cluster that in turn encapsulates a pair of pyrovanadate templates. Expand
High-nuclearity silver ethynide clusters assembled with phosphonate and metavanadate precursors.
Three unprecedented mixed-metal giant clusters with the silver(I) tert-butylethynide moiety and various phosphonate-functionalized oxovanadate building blocks are isolated. Expand
A three-dimensional complex with a one-dimensional cobalt-hydroxyl chain based on planar nonanuclear clusters showing spin-canted antiferromagnetism.
The results suggest that reasonable design and choice of large carboxylate ligandbased on a specific scaffold could be effective for the construction of magnetic materials based on a novel 1D magnetic chain. Expand
A new exploration towards aminothiazolquinolone oximes as potentially multi-targeting antibacterial agents: Design, synthesis and evaluation acting on microbes, DNA, HSA and topoisomerase IV.
The preliminarily mechanism exploration revealed that compound 10b could not only exert efficient membrane permeability by interfering with the integrity of cells, bind with topoisomerase IV-DNA complex through hydrogen bonds and π-π stacking, but also form a steady biosupramolecular complex by intercalating into DNA to exert the efficient antibacterial activity.

Silver(I) ethynide coordination networks and clusters assembled with tert-butylphosphonic acid.
Single-crystal X-ray analysis revealed that complexes 1 and 2 display different layer-type coordination networks, while 3 and 4 contain high-nuclearity silver(I) composite clusters enclosing nitrate and chloride template ions, respectively, that are supported by (t)BuPO(3)(2-) ligands. Expand
Monoorganooxotin cage, diorganotin ladders, diorganotin double chain and triorganotin single chain formed with phosphonate and arsonate ligands.
The solvothermal reaction of n-BuSn(O)OH with PhPO(3)H(2) afforded the hexanuclear monoorganooxotin phosphonate cage, which contains both sulfonate and arsonate ligands. Expand
Isolation and Crystallographic Characterization of Lu3 N@C2n (2n=80-88): Cage Selection by Cluster Size.
Experimental evidence is presented to establish the size effect of the internal metallic cluster on selecting the outer cage of endohedral metallofullerenes (EMFs) by using a medium-sized metal, lutetium, which possesses an ionic radius between Sc and Gd. Expand
