Abstract

Molecular growth processes utilizing polyoxometalate-based building blocks with silver connecting units have been used to produce four new materials: <b>1</b>, [Ag<sub>3</sub>(bhepH)<sub>8</sub>(W<sub>11.5</sub>Na<sub>0.5</sub>O<sub>40</sub>P)<sub>2</sub>]·8H<sub>2</sub>O (bhep = <i>N,N</i>-bis(2-hydroxyethyl)piperazine); <b>2</b>, [Ag<sub>4</sub>(DMSO)<sub>8</sub>(Mo<sub>8</sub>O<sub>26</sub>)]n; <b>3</b>, {Ag<sub>3</sub>[MnMo<sub>6</sub>O<sub>18</sub>{(OCH<sub>2</sub>)<sub>3</sub>CNH<sub>2</sub>}<sub>2</sub>(DMSO)5]·3(DMSO)}<sub>n</sub>; <b>4</b>, {Ag<sub>3</sub>[MnMo<sub>6</sub>O<sub>18</sub>{(OCH<sub>2</sub>)<sub>3</sub>CNH2}<sub>2</sub>(DMSO)<sub>6</sub>(CH<sub>3</sub>CN)<sub>2</sub>]·DMSO}<sub>n</sub>. The compounds were characterised using single crystal X-ray crystallography, elemental analysis, IR, TGA, DSC, and compounds <b>2–4</b> were imaged on silicon substrates using scanning electron microscopy. Compound <b>1</b> represents a 0D dimer connected by silver ions but was also found to form channels facilitated by the hydrogen bonding between the protonated [bhepH]<sup>+</sup> ligand and the cluster, and complex <b>2</b> forms 2D layered networks, whereas both compounds <b>3</b> and <b>4</b> form 1D networks; these networks are all connected by Ag(I) ions. Thermal studies show that the stabilities of compounds <b>2–4</b> are affected by the linking Ag(I) ions and the DMSO ligands and EM studies on compounds <b>3</b> and <b>4</b> showed the formation of fibres on silicon substrates.
