Abstract
AbstractThe oligomeric cluster complex {Ir3Gd11}Br15 was first obtained from a reaction of Gd, GdBr3 and Ir in a 3:4:1 molar ratio at 1123 K. The crystals belong to the hexagonal space group P63/m with lattice parameters a = 1276.79(14) pm and c = 1286.92(16) pm. The structure features isolated {Ir3Gd11} cluster trimers, which are built up by three face‐sharing gadolinium octahedra each centered by an iridium atom. The endohedral iridium atoms form a triangle with Ir–Ir distances of 295.51(11) pm. Thus, the {Ir3Gd11} cluster is topologically equivalent to the suboxide {O3Cs11}. The {Ir3Gd11} clusters are encapsulated in a coordination sphere of 30 bromide ions, which act as bridging ligands according to the formulation {Ir3Gd11}Bri–i12/2Bri–a9/2Bra–i9/2. In {Ir3Gd11}Br15 there are 45 electrons present for intracluster bonding.
