Metal-containing polymers have great potential as catalysts since they can combine the simplicity of use of insoluble heterogeneous catalysts with the chemical regularity and specificity of homogeneous catalysts. 1 In particular, metal-organic polymers are apt to preferentially coordinate small molecules, which can enter the pores in the network. In cases where coordination is reversible, catalytic delivery of small molecules is possible. In contrast to their molecular analogs, networked catalysts are typically insoluble and therefore readily filterable, an advantage during product purification. As part of our on-going studies of Cu(I) coordination polymers, 2 we are investigating the reactions of copper(I) halides with bridging ligands in the presence of carbon monoxide. Numerous Cu(I)-carbonyl complexes are known; 3–6 however, only a few polymeric crystal structures containing Cu–CO have been reported. These include that of CuCl(CO) itself, which forms a hexagonal honeycomb layer structure via triply bridging chloride. 4 The use of polydentate anions such as ethylsulfonate, hydrogen sulfonate, and trichloroacetate with Cu(CO) + produces chain structures. 5 Finally, [Cu(CO)(NCMe)(1,2-di-2- pyridylethylene)] + represents the only reported amine-bridged polymer of Cu(CO). 6
