Title: Materials Data on Ta3Br7 by Materials Project

Abstract

Ta3Br7 crystallizes in the orthorhombic Cmce space group. The structure is two-dimensional and consists of two Ta3Br7 sheets oriented in the (0, 1, 0) direction. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a distorted square co-planar geometry to four Br atoms. There are two shorter (2.60 Å) and two longer (2.61 Å) Ta–Br bond lengths. In the second Ta site, Ta is bonded to five Br atoms to form distorted corner-sharing TaBr5 square pyramids. There are a spread of Ta–Br bond distances ranging from 2.61–2.88 Å. There are five inequivalent Br sites. In the first Br site, Br is bonded in a 2-coordinate geometry to two equivalent Ta atoms. In the second Br site, Br is bonded in a 2-coordinate geometry to two equivalent Ta atoms. In the third Br site, Br is bonded in a 2-coordinate geometry to two Ta atoms. In the fourth Br site, Br is bonded in a distorted bent 150 degrees geometry to two equivalent Ta atoms. In the fifth Br site, Br is bonded in a 2-coordinate geometry to two Ta atoms.
