Abstract
- A 90-nucleus silver cluster (SD/Ag38) cocapped by tBuC<subscript>6</subscript>H<subscript>4</subscript>S<superscript>−</superscript> and PhCOO<superscript>−</superscript> ligands was synthesized using hetero-anion template method. Single-crystal X-ray diffraction (SCXRD) revealed a 90-nucleus metallic dumbbell-like core constructed by two large W<subscript>5</subscript>O<subscript>19</subscript>@Ag<subscript>38</subscript> heads sandwiching one slender (SO<subscript>4</subscript>)<subscript>2</subscript>@Ag<subscript>14</subscript> waist. Both W<subscript>5</subscript>O<subscript>19</subscript><superscript>8−</superscript> and SO<subscript>4</subscript><superscript>2−</superscript> templates were in situ generated and synergistically induced the formation of the largest known anion-templated silver cluster. Although SD/Ag38 is emission-silent at room temperature, increasingly brighter near-infrared (NIR) emission at ca. 742 nm was detected on cooling from 293 to 93 K. [ABSTRACT FROM AUTHOR]
