Bis(μ‐2,2,6,6,10,10‐hexamethyl‐4,8‐dioxaundecanedioato‐ O 1 , O 11 : O 1' , O 11' )bis(pyridine‐ N )dirhodium(II)( Rh — Rh )

The title compound, [Rh₂(C₁₅H₂₆O₆)₂(C₅H₅N)₂], lies about an inversion centre which is at the midpoint of the Rh-Rh bond. The polyether dicarboxylate ligands bridge the Rh atoms and function as macrocyclic chelates to the Rh-Rh unit. A pyridine molecule is axially coordinated to each Rh atom completing the octahedral coordination. Main dimensions are Rh-Rh 2.4017 (2), Rh-O 2.0367 (9)-2.0405 (9), Rh-N 2.2540 (11) Å and Rh-Rh-N 178.59 (3)°
