摘要：
124 silver atoms and 57 selenido ligands are contained in the cluster complex [Ag124Se57 (SePtBU2)4 Cl6(tBU2P (CH2)3PtBu2)12]. The molecule has an approximate diameter of 3 nm. The selenium substructure (see picture) is formed of spheres with a central Frank - Kasper polyhedron (red). Apart from this silver selenide cluster, three smaller silver-selenide cluster complexes are described.
