Abstract

An earlier study describing the exchange of the μ-acetato ligands of Re2(μ-O2CCH3)Cl4(μ-dppm)2 (1) and cis-Re2(μ-O2CCH3)2Cl2(μ-dppm)2 (2) by dicarboxylic acids has been expanded to include reactions with the monocarboxylic acid isonicotinic acid, and the dicarboxylic acids adipic acid, 4,4′-biphenyldicarboxylic acid, fumaric acid, trans-1,4-cyclohexanedicarboxylic acid and 1,1′-ferrocenedicarboxylic acid. Further examples of complexes that are “dimers-of-dimers” and triangular supramolecular assemblies involving retention of the basic electronic and molecular structures of the dirhenium units present in 1 and 2 have been obtained. In addition, the dirhenium complexes Re2(μ-O2CC6H4N)Cl4(μ-dppm)2 (7) and cis-Re2(μ-O2C6H10CO2Et)2Cl2(μ-dppm)2 (11) have been isolated, as well as the trimetallic complex cis-Re2Cl2(μ-dppm)2[(μ-O2CC5H4)2Fe] (14) that is formed from the reaction of 2 with (C5H4CO2H)2Fe. The crystal structures of 7, 11 and 14 are reported.
