Abstract

La12C6I17 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are six inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to four C+3.17- and four I1- atoms. There are a spread of La–C bond distances ranging from 2.75–2.91 Å. There are two shorter (3.34 Å) and two longer (3.37 Å) La–I bond lengths. In the second La3+ site, La3+ is bonded to one C+3.17- and five I1- atoms to form distorted LaCI5 octahedra that share a cornercorner with one LaCI5 octahedra and edges with two equivalent LaC4I4 hexagonal bipyramids. The corner-sharing octahedral tilt angles are 1°. The La–C bond length is 2.35 Å. There are a spread of La–I bond distances ranging from 3.21–3.45 Å. In the third La3+ site, La3+ is bonded in a 7-coordinate geometry to three C+3.17- and four I1- atoms. There are a spread of La–C bond distances ranging from 2.41–2.79 Å. There are a spread of La–I bond distances ranging from 3.29–3.45 Å. In the fourth La3+ site, La3+ is bonded in a 6-coordinate geometry to two C+3.17- and four I1- atoms.
