Abstract

La10C4I15 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent La3+ sites. In the first La3+ site, La3+ is bonded to one C+3.75- and five I1- atoms to form distorted LaCI5 octahedra that share corners with two LaC2I5 pentagonal bipyramids, edges with two LaCI5 octahedra, and edges with two LaC2I5 pentagonal bipyramids. The La–C bond length is 2.36 Å. There are a spread of La–I bond distances ranging from 3.22–3.51 Å. In the second La3+ site, La3+ is bonded to two C+3.75- and five I1- atoms to form distorted LaC2I5 pentagonal bipyramids that share a cornercorner with one LaCI5 octahedra, corners with three LaC2I5 pentagonal bipyramids, edges with three LaCI5 octahedra, and a faceface with one LaC2I5 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 12°. There are one shorter (2.64 Å) and one longer (2.65 Å) La–C bond lengths. There are a spread of La–I bond distances ranging from 3.20–3.57 Å. In the third La3+ site, La3+ is bonded to two C+3.75- and five I1- atoms to form distorted LaC2I5 pentagonal bipyramids that share a cornercorner with one LaCI5 octahedra, corners with two equivalent LaC2I5 pentagonal bipyramids, edges with three LaCI5 octahedra, anmore »« less
