The silver salts of 1-adamantanethiol (AdSH) and furan-2-ylmethanethiol (FurCH2SH) were successfully applied as building blocks for ligand-protected Ag2S nanoclusters. The reaction of the silver thiolates [AgSAd]x and [AgSCH2Fur]x with S(SiMe3)2 and 1,5-bis(diphenylphosphino) pentane (dpppt) afforded three different clusters with 58, 94 and, 190 silver atoms. The intensely colored compounds [Ag58S13(SAd)32] (1), [Ag94S34(SAd)26(dpppt)6] (2), and [Ag190S58(SCH2Fur)74(dpppt)8] (3) were structurally characterized by single-crystal X-ray diffraction and exhibit different cluster core geometries and ligand shells. The diameters of the well-defined sphere-shaped nanoclusters range from 2.2 nm to 3.5 nm. [ABSTRACT FROM AUTHOR]

An M4L4 type metal-organic cage (MOC-19) has been synthesized from the one-pot reaction of tri(pyridinylmethylene)phenylbenzeneamine (TPBA) with hydrated Zn(ClO4)2 under mild conditions and characterized by single-crystal X-Ray diffraction. Iodine capture studies show that the porous crystals of MOC-19 exhibit a versatile behavior to accumulate iodine species not only in vapor (for I2) but also in solution (for I2 and I3−), and anion-exchange experiments indicate the capacity to extract IO3− anions from aqueous solution. Enrichment of iodine species from KI/I2 aqueous solution proceeds facilely, revealing a pseudo-second-order kinetics of I3− adsorption. Furthermore, the electrical conductivity of MOC-19 single crystals could be significantly altered by I2 inclusion. [ABSTRACT FROM AUTHOR]
