Abstract

NdBiRu2O7 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Nd3+ is bonded to eight O2- atoms to form distorted NdO8 hexagonal bipyramids that share edges with two equivalent NdO8 hexagonal bipyramids, edges with four equivalent BiO8 hexagonal bipyramids, and edges with six RuO6 octahedra. There are a spread of Nd–O bond distances ranging from 2.26–2.58 Å. There are two inequivalent Ru4+ sites. In the first 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 NdO8 hexagonal bipyramids. The corner-sharing octahedra tilt angles range from 47–48°. There are two shorter (2.01 Å) and four longer (2.02 Å) Ru–O bond lengths. 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 NdO8 hexagonal bipyramids, and edges with four equivalent BiO8 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 47°. 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 edgesmore »« less
