One- and Two-Dimensional Silver-Coordination Networks Containing π-Sandwiched Silver−Silver Interactions

The self-assembly of coordination networks from reaction of 2,4,6-trimesityl-1,3,5-triazine and silver(I) trifluoroacetate
is described. A one-dimensional linear polymer is formed from solutions deficient in silver while a two-dimensional,
graphite-like sheet is formed from solutions containing 3 equiv of silver per triazine. The structurally similar networks
both contain triazine rings separated by two trifluoroacetate-bridged silver atoms. The two silver atoms are effectively
sandwiched between two mesityl rings with intermediate arene−silver interactions. The silver−silver bond lengths
are 2.9731(4) and 2.9246(5) Å in the one-dimensional network and 2.8842(4) Å in the two-dimensional network.
