Title: Materials Data on Tb4SiBr6 by Materials Project

Abstract

Tb4SiBr6 is trigonal omega-derived structured and crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. there are two inequivalent Tb sites. In the first Tb site, Tb is bonded to one Si and five Br atoms to form a mixture of corner and edge-sharing TbSiBr5 octahedra. The corner-sharing octahedra tilt angles range from 0–48°. The Tb–Si bond length is 2.74 Å. There are four shorter (2.91 Å) and one longer (3.02 Å) Tb–Br bond lengths. In the second Tb site, Tb is bonded to two equivalent Si and four Br atoms to form a mixture of corner and edge-sharing TbSi2Br4 octahedra. The corner-sharing octahedra tilt angles range from 0–48°. Both Tb–Si bond lengths are 2.80 Å. There are two shorter (2.97 Å) and two longer (2.99 Å) Tb–Br bond lengths. Si is bonded to six Tb atoms to form edge-sharing SiTb6 octahedra. There are three inequivalent Br sites. In the first Br site, Br is bonded in a distorted T-shaped geometry to three Tb atoms. In the second Br site, Br is bonded in a distorted T-shaped geometry to three Tb atoms. In the third Br site, Br is bonded in a distorted T-shaped geometry to three Tbmore » atoms.« less
