Abstract

Bi4(TeSe)3 crystallizes in the monoclinic Cm space group. The structure is three-dimensional. there are four inequivalent Bi3+ sites. In the first Bi3+ site, Bi3+ is bonded to one Te2- and five Se2- atoms to form BiTeSe5 octahedra that share corners with three equivalent BiTe3Se3 octahedra and edges with nine BiTeSe5 octahedra. The corner-sharing octahedral tilt angles are 1°. The Bi–Te bond length is 3.10 Å. There are a spread of Bi–Se bond distances ranging from 2.91–3.12 Å. In the second Bi3+ site, Bi3+ is bonded to two equivalent Te2- and four Se2- atoms to form BiTe2Se4 octahedra that share corners with three equivalent BiTe3Se3 octahedra and edges with nine BiTeSe5 octahedra. The corner-sharing octahedral tilt angles are 1°. Both Bi–Te bond lengths are 3.07 Å. There are a spread of Bi–Se bond distances ranging from 2.88–3.14 Å. In the third Bi3+ site, Bi3+ is bonded to three Te2- and three Se2- atoms to form BiTe3Se3 octahedra that share corners with three equivalent BiTe2Se4 octahedra and edges with nine BiTeSe5 octahedra. The corner-sharing octahedral tilt angles are 1°. All Bi–Te bond lengths are 3.07 Å. There are two shorter (3.11 Å) and one longer (3.12 Å) Bi–Se bond lengths. In themore »« less
