A Novel Water-Soluble Hexanuclear Bismuth Oxido Cluster – Synthesis, Structure and Complexation with Polyacrylate (Eur. J. Inorg. Chem. 30/2010)

The cover picture shows a novel hexanuclear bismuth oxido cluster [Bi6O4(OH)4(OTf)6], which forms a 1D coordination polymer in the solid state but is highly soluble in water and polar organic solvents. The reaction of the bismuth oxido cluster with sodium polyacrylate gave a nano-sized hybrid material still soluble in aqueous solution. A snapshot from a molecular dynamics simulation is shown as an example of the apparent complexation of [Bi6O4(OH)4]6+ by polyacrylate in water. The synthesis and structure of [Bi6O4(OH)4(OTf)6] as well as its complexation with polyacrylate are reported in the article by D. Zahn, M. Mehring et al. on p. 4763 ff.
