Several new 1D coordination polymers have been synthesised using the anionic ligand carbamoyldicyanomethanide, C(CN)(2)(CONH2)(-) (cdm). The polymeric complexes [Cu(cdm)(2)(py)(2)]center dot 2MeOH (1), [Cu(cdm)(2)(4-Etpy)(2)]center dot 2MeOH (2), [Cu(cdm)(2)(3,5-Me(2)pzH)(2)]center dot 2MeOH (3) and [Cu(cdm)(2)(3-HOCH(2)py)(2)]center dot 2MeOH (4) (py = pyridine; 3,5-Me(2)pzH = 3,5-dimethylpyrazole) contain Cu(II) atoms bridged by mu(2)-(N,N ) cdm ligands between equatorial and axial coordination sites. The use of monodentate co-ligands brings about polymeric products, in contrast to the use previously of chelating co-ligands which facilitate the formation of discrete products. These I D polymeric complexes are connected by hydrogen bonding between the amide functionalities and the lattice solvent. In the Structures of 3 and 4 the neutral ligands also contain hydrogen bond donor groups that supplement the amide ring motif. Two other complexes have been obtained that are polymeric chains of alkoxide-bridged Cu(II) dimers. The complexes [Cu(cdm)(MeO)(2-amp)] (5) and [Cu(cdm)(dmap)] (6) (2-amp = 2-(aminomethyl)pyridine and dmap = dimethylaminopropoxide) are remarkably similar despite the different ligands that they contain. Bridging between dimers is via mu(2)-(N,O) cdm ligands, consequently altering the nature of the hydrogen bonding between adjacent chains compared to the simple polymeric species 1-3.
