Two novel heterobimetallic supramolecular polymers, [CuAg 4 (CN) 6 (tacn)] n ( 1 ) and [CuAu 2 (CN) 4 (tacn)] n ( 2 ) (tacn = 1,4,7‐triazacyclononane), have been synthesised from the building block [Cu(tacn)] 2+ , together with [Ag(CN) 2 ] − (for 1 ) and [Au(CN) 2 ] − (for 2 ). The large difference in structural type between 1 and 2 is probably due to the fact that the Ag I centre is three‐coordinate and trigonal whereas the Au I centre is linear. Metal−metal interactions play an important role in the formation of the supramolecular framework of 1 and the novel topology of 2 . (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
