Abstract
- A new mixed-valent silver complex [Ag<superscript>II</superscript>(tmc)][Ag<superscript>II</superscript>(tmc)(H<SUB>2</SUB>O)]<SUB>2</SUB>·[Ag<superscript>I</superscript><SUB>11</SUB>(C<SUB>2</SUB>)(CF<SUB>3</SUB>CO<SUB>2</SUB>)<SUB>12</SUB>(H<SUB>2</SUB>O)<SUB>4</SUB>]<SUB>2</SUB> (tmc = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) was synthesized by adding tmc to a concentrated aqueous solution of silver trifluoroacetate containing dissolved silver acetylide. Single-crystal X-ray analysis revealed that the resulting [Ag<superscript>II</superscript>(tmc)]<superscript>2+</superscript> and [Ag<superscript>II</superscript>(tmc)(H<SUB>2</SUB>O)]<superscript>2+</superscript> complex cations induce the self-assembly of a centrosymmetric anionic cluster dimer from the Ag(I), C<SUB>2</SUB><superscript>2−</superscript> and CF<SUB>3</SUB>CO<SUB>2</SUB><superscript>−</superscript> species. A new type of cluster core [C<SUB>2</SUB>@Ag<SUB>8</SUB>]Ag was observed, which takes the form of a bicapped trigonal prism with a pendant silver atom attached to one edge.
