Anion Templated Synthesis of Silver(I)-Ethynide Dithiophosphate Clusters
No full textReaction
of AgCC<sup><i>t</i></sup>Bu with (EtO)<sub>2</sub>PS<sub>2</sub>Na at room temperature leads to the isolation
of two new silver(I)-ethynide compounds incorporating the dithiophosphate
ligand, namely, {CO<sub>3</sub>@(Ag<sub>3</sub>)<sub>4</sub>(CC<sup><i>t</i></sup>Bu)<sub>4</sub>(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>6</sub>}·0.5H<sub>2</sub>O (<b>1</b>) and {(CO<sub>3</sub>)<sub>2</sub>@Ag<sub>26</sub>(CC<sup><i>t</i></sup>Bu)<sub>16</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>}·2(OH)·4MeOH·6H<sub>2</sub>O (<b>2</b>). Besides,
we obtain another three silver(I)-ethynide clusters S@Ag<sub>11</sub>(CC<sup><i>t</i></sup>Bu)<sub>2</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>7</sub> (<b>3</b>), {S@Ag<sub>14</sub>(CCPh)<sub>8</sub>[(EtO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>(TMEDA)<sub>2</sub>}·5MeOH (<b>4</b>), and {S@Ag<sub>14</sub>(CCPh)<sub>8</sub>[(<sup><i>i</i></sup>PrO)<sub>2</sub>PS<sub>2</sub>]<sub>4</sub>(TMEDA)<sub>2</sub>}·7CH<sub>3</sub>OH (<b>5</b>), with AgCCR (R= <sup><i>t</i></sup>Bu, Ph) and (RO)<sub>2</sub>PS<sub>2</sub>Na (R= Et, <sup><i>i</i></sup>Pr) as the starting materials. Complexes <b>1</b>–<b>2</b> are templated by a carbonate anion in situ
generated from the fixation of atmospheric CO<sub>2</sub> in a basic
TMEDA-containing solution, and TMEDA can also lead to the disassembly
of dithiophosphate to give a sulfide ion as the template for the generation
of <b>3</b>–<b>5</b>
Structure-Directing Role of Phosphonate in the Synthesis of High-Nuclearity Silver(I) Sulfide-Ethynide-Thiolate Clusters

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 <sup><i>t</i></sup>BuCC⊃Ag<sub>3</sub>, <sup><i>t</i></sup>BuCC⊃Ag<sub>4</sub>, and 2<sup><i>t</i></sup>BuCC⊃Ag<sub>7</sub> are bridged by <sup><i>t</i></sup>BuS<sup>–</sup> ligands to engender respective silver(I) ethynide-thiolate clusters
functioning as integral shell components, which are supported by phosphonate
ligands. In each silver(I) sulfide-ethynide-thiolate cluster, a different
encapsulated silver sulfide cluster serves as a core template
