The cover picture shows the characteristic crystal form of elemental bismuth in the background and a perspective view of the crystal structure Bi(Bi 9 )[NbCl 6 ] 3 containing three‐capped trigonal prismatic Bi 9 5+ clusters. The Bi + cations in the channels made up of the octahedral halometalate anions are disordered and can be treated in different ways in the crystallographic description. A remarkable feature of the compound is the paramagnetic behaviour, which shows the presence of Nb in the less common oxidation state +IV. Details are discussed in the article by J. Beck and T. Hilbert on p. 2019 ff.
