The synthesis and characterization of compound [Rh₂(O₂CEt)₄(H₂O)₂] (1) and one-dimensional heterobimetallic polymers K_n{Rh₂(O₂CEt)₄[Au(CN)₂]}_n (2) and K_n{Rh₂(O₂CMe)₄[Au(CN)₂]}_n路4nH₂O (3), constructed from dirhodiumtetracarboxylato units, [Rh₂(O₂CR)₄]⁺, and dicyanoaurate, [Au(CN)₂]^{鈭?/sup>, fragments are described. In both compounds 2 and 3 the resulting polymeric chains are nonlinear and have in common similar structural parameters, although the solid state supramolecular arrangement is very different. These structural differences explain the fact that complex 2 displays aurophilic interactions while this type of interactions are absent in complex 3. As a result, compound 2 shows rich blue luminescent properties whereas compound 3 is not luminescent. The electrical conductivity in solid state of compounds 2 and 3 is also studied.}
