Heteronuclear Dirhodium-Gold Anionic Complexes: Polymeric Chains and Discrete Units
In this article, we report on the synthesis and characterization of the tetracarboxylatodirhodium(II) complexes [Rh<sub>2</sub>(μ–O<sub>2</sub>CCH<sub>2</sub>OMe)<sub>4</sub>(THF)<sub>2</sub>] (<b>1</b>) and [Rh<sub>2</...

| description | In this article, we report on the synthesis and characterization of the tetracarboxylatodirhodium(II) complexes [Rh<sub>2</sub>(μ–O<sub>2</sub>CCH<sub>2</sub>OMe)<sub>4</sub>(THF)<sub>2</sub>] (<b>1</b>) and [Rh<sub>2</sub>(μ–O<sub>2</sub>CC<sub>6</sub>H<sub>4</sub>–<i>p</i>–CMe<sub>3</sub>)<sub>4</sub>(OH<sub>2</sub>)<sub>2</sub>] (<b>2</b>) by metathesis reaction of [Rh<sub>2</sub>(μ–O<sub>2</sub>CMe)<sub>4</sub>] with the corresponding ligand acting also as the reaction solvent. The reaction of the corresponding tetracarboxylato precursor, [Rh<sub>2</sub>(μ–O<sub>2</sub>CR)<sub>4</sub>], with PPh<sub>4</sub>[Au(CN)<sub>2</sub>] at room temperature, yielded the one-dimensional polymers (PPh<sub>4</sub>)<i><sub>n</sub></i>[Rh<sub>2</sub>(μ–O<sub>2</sub>CR)<sub>4</sub>Au(CN)<sub>2</sub>]<i><sub>n</sub></i> (R = Me (<b>3</b>), CH<sub>2</sub>OMe (<b>4</b>), CH<sub>2</sub>OEt (<b>5</b>)) and the non-polymeric compounds (PPh<sub>4</sub>)<sub>2</sub>{Rh<sub>2</sub>(μ–O<sub>2</sub>CR)<sub>4</sub>[Au(CN)<sub>2</sub>]<sub>2</sub>} (R = CMe<sub>3</sub> (<b>6</b>), C<sub>6</sub>H<sub>4</sub>–<i>p</i>–CMe<sub>3</sub> (<b>7</b>)). The structural characterization of <b>1</b>, <b>3·2CH<sub>2</sub>Cl<sub>2</sub></b>, <b>4·3CH<sub>2</sub>Cl<sub>2</sub></b>, <b>5</b>, <b>6</b>, and <b>7·2OCMe<sub>2</sub></b> is also provided with a detailed description of their crystal structures and intermolecular interactions. The polymeric compounds <b>3·2CH<sub>2</sub>Cl<sub>2</sub></b>, <b>4·3CH<sub>2</sub>Cl<sub>2</sub></b>, and <b>5</b> show wavy chains with Rh–Au–Rh and Rh–N–C angles in the ranges 177.18°–178.69° and 163.0°–170.4°, respectively. A comparative study with related rhodium-silver complexes previously reported indicates no significant influence of the gold or silver atoms in the solid-state arrangement of these kinds of complexes. |
