Abstract

Gd3Bi(Ru2O7)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Gd3+ is bonded to eight O2- atoms to form distorted GdO8 hexagonal bipyramids that share edges with two equivalent BiO8 hexagonal bipyramids, edges with four equivalent GdO8 hexagonal bipyramids, and edges with six RuO6 octahedra. There are a spread of Gd–O bond distances ranging from 2.22–2.54 Å. There are two inequivalent Ru4+ sites. In the first Ru4+ site, Ru4+ is bonded to six equivalent O2- atoms to form RuO6 octahedra that share corners with six equivalent RuO6 octahedra and edges with six equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 49°. All Ru–O bond lengths are 2.01 Å. In the second Ru4+ site, Ru4+ is bonded to six O2- atoms to form RuO6 octahedra that share corners with six RuO6 octahedra, edges with two equivalent BiO8 hexagonal bipyramids, and edges with four equivalent GdO8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 49°. There are four shorter (2.00 Å) and two longer (2.02 Å) Ru–O bond lengths. Bi3+ is bonded to eight O2- atoms to form distorted BiO8 hexagonal bipyramids that share edges with six equivalent GdO8 hexagonal bipyramids and edges with six equivalent RuO6 octahedra.more »« less
