Tetrakis(tert-butyl isocyanide-2C)dichloro-1Cl,3Cl-di--cyano-1N:2C;2C:3N-bis[1,3(⁴)-cycloocta-1,5-diene]dirhodium(I)ruthenium(II)

Abstract: The title compound, [Rh₂Ru(CN)₂Cl₂(C₈H₁₂)₂(C₅H₉N)₄], was obtained from the reaction of the chloro(1,5-cyclooctadiene)rhodium(I) dimer with trans-dicyanotetra(tert-butyl isocyanide)ruthenium(II) by cleavage of the chloro bridges in the dimeric rhodium starting complex. The molecular structure shows the Ru atom in a nearly ideal octahedral coordination geometry, whereas the Rh atoms are situated in square-planar ligand environments. The central ruthenium ion is located on a crystallographic twofold axis. The crystal structure is realized by infinite chains of the trinuclear complex units which are connected by C-HCl interactions. These chains are further linked by another C-HCl interaction to produce the observed three-dimensional structure.
