Condensed Double‐Chain Cluster Complexes with Seven‐Coordinate Endohedral Iridium Atoms in {Ir₂Gd₅}Br₅

Abstract

The new condensed double-chain cluster complex compound {Ir 2 Gd 5 }Br 5 was obtained from a reaction of GdBr 3 with metallic gadolinium and iridium at elevated temperatures. The thin black needles crystallize with the orthorhombic crystal system, space group Pnma (no. 62); a = 1255.4(1) pm, b = 414.05(3) pm, c = 2633.8(3) pm, Z = 4, R 1 /wR 2 = 0.0504/0.0346 for all data.
