N2 - Molecular growth processes utilizing polyoxometalate-based building blocks with silver connecting units have been used to produce four new materials: 1, [Ag3(bhepH)8(W11.5Na0.5O 40P)2]·8H2O (bhep = N,N′-bis(2- hydroxyethyl)piperazine); 2, [Ag4(DMSO)8(Mo 8O26)]n; 3, {Ag3[MnMo 6O18{(OCH2)3CNH2} 2(DMSO)5]·3(DMSO)}n; 4, {Ag 3[MnMo6O18{(OCH2) 3CNH2}2(DMSO)6(CH 3CN)2]·DMSO}n. The compounds were characterised using single crystal X-ray crystallography, elemental analysis, IR, TGA, DSC, and compounds 2-4 were imaged on silicon substrates using scanning electron microscopy. Compound 1 represents a 0D dimer connected by silver ions but was also found to form channels facilitated by the hydrogen bonding between the protonated [bhepH]+ ligand and the cluster, and complex 2 forms 2D layered networks, whereas both compounds 3 and 4 form 1D networks; these networks are all connected by Ag(i) ions. Thermal studies show that the stabilities of compounds 2-4 are affected by the linking Ag(i) ions and the DMSO ligands and EM studies on compounds 3 and 4 showed the formation of fibres on silicon substrates.
