Self-Assembly of One- and Two-Dimensional Coordination Polymers with Quinonoid Backbones Featuring Coinage Metals as Nodes

We report the use of the organometallic linker [Cp*Ir(η<sup>4</sup>-benzoquinone)] (<b>1b</b>) L<sup>Ir</sup> to construct novel supramolecular one- and two-dimensional (1D and 2D) coordination polymers {[Cu<sub>2</sub>(L<sup>Ir</sup>)<sub>2</sub>(CH<sub>3</sub>CN)(OTf)<sub>2</sub>][L<sup>Ir</sup>](OTf)}<i><sub>n</sub></i> (<b>3</b>) and {[Ag<sub>2</sub>(CH<sub>3</sub>CN)<sub>2</sub>][L<sup>Ir</sup>]<sub>2</sub>(OTf)<sub>2</sub>}<i><sub>n</sub></i> (<b>4</b>). Complex <b>3</b> formed a zigzag chain of Cu(I) and Cu(II) centers connected through irido-quinonoid backbones, while complex <b>4</b> exhibited argentopilic Ag---Ag d<sup>10</sup>---d<sup>10</sup> contacts at <i>d</i> = 3.638 Å and C---H/π interactions between the 1D chain neighbors.
