description: SmB7H7O17 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Sm is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Sm–O bond distances ranging from 2.42–2.49 Å. There are seven inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.36–1.40 Å. In the second B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–O bond distances ranging from 1.35–1.40 Å. In the third B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There is two shorter (1.48 Å) and two longer (1.49 Å) B–O bond length. In the fourth B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra.
