The cover picture shows a model of the cluster [Cu 29 Te 16 (P i Pr 3 ) 12 ], whose structure can be described with the Frank–Kasper polyhedra known for intermetallic phases. A red Te 15 Frank–Kasper polyhedron with 26 triangular faces is penetrated by the blue Cu 29 cluster, and in the center of the total cluster the sixteenth Te atom is situated, to which three of the copper atoms are bound. The P i Pr 3 bound Cu atoms are located above twelve of the Te triangular faces, a further fourteen lie below the other faces. More about the diversity of clusters obtained from CuCl, Te(SiMe 3 ) 2 , and phosphanes is reported by D. Fenske and J.‐C. Steck on pages 238 ff. – In this issue an analysis of the referee system of “Angewandte Chemie” by H.‐D. Daniel can be found on pages 234 ff., which is certainly of interest for all chemists.
