Abstract
AbstractThe cover picture shows a space‐filling model of part of the crystal structure of [Lu(Db18c6)(H2O)3(thf)6]4(I3)2(I5)6(I8)(I12). The cations consist of a central nine‐coordinate lutetium(III) ion surrounded by one dibenzo‐18‐crown‐6 and three water molecules to which two hydrogen‐bonded tetrahydrofuran molecules are attached. These large cations fill space that is created by a three‐dimensional polyiodide network, which in itself is built from four different polyiodide ions, (I3)‐, (I5)‐, (I8)2‐, and (I12)2‐. Crystals were obtained by oxidation of lutetium metal with iodine in the presence of Db18c6 and thf as the solvent containing traces of water. Christine Walbaum obtained this new compound during a six‐month leave at Monash University, Clayton, Victoria. Clayton is at the outskirts of Greater Melbourne whose central business district and the waterfront constitute the background of the cover picture. More details concerning [Lu(Db18c6)(H2O)3(thf)6]4(I3)2(I5)6(I8)(I12) are discussed in the article by Walbaum et al. on pp. 1444ff.
