Descripción
Sumario:The title compound, tetrakis(μ-3,4,5-triethoxy­benzoato-κ<sup>2</sup>O:O′)­bis­[(pyrazine-κN)­rhodium(II)](Rh—Rh), [Rh<sub>2</sub>(C<sub>13</sub>H<sub>17</sub>O<sub>5</sub>)<sub>4</sub>(C<sub>4</sub>H<sub>4</sub>N<sub>2</sub>)<sub>2</sub>], crystallizes on an inversion centre in the triclinic space group P ‾1. The equatorial carboxyl­ate ligands bridge the two Rh<sup>II</sup> atoms, giving a binuclear lantern-like structure. The pyrazine mol­ecules occupy the two axial coordination sites. The phenyl rings are tilted by ca 10° with respect to the attached carboxyl­ate groups. The pyrazine planes have a torsion angle of ca 19° around the Rh—N bond with respect to the plane of the nearer carboxyl­ate group and are not coplanar with the Rh—Rh bond.
