Materials Data on Ta3In2Cl9 by Materials Project

Abstract

Ta3In2Cl9 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded to five Cl atoms to form distorted corner-sharing TaCl5 square pyramids. There are a spread of Ta–Cl bond distances ranging from 2.47–2.66 Å. In the second Ta site, Ta is bonded to five Cl atoms to form distorted corner-sharing TaCl5 square pyramids. There are a spread of Ta–Cl bond distances ranging from 2.47–2.62 Å. In is bonded in a 3-coordinate geometry to three Cl atoms. There are a spread of In–Cl bond distances ranging from 3.07–3.15 Å. There are six inequivalent Cl sites. In the first Cl site, Cl is bonded in a distorted trigonal non-coplanar geometry to one Ta and two equivalent In atoms. In the second Cl site, Cl is bonded in a 2-coordinate geometry to two equivalent Ta atoms. In the third Cl site, Cl is bonded in a distorted trigonal planar geometry to one Ta and two equivalent In atoms. In the fourth Cl site, Cl is bonded in a 2-coordinate geometry to two Ta atoms. In the fifth Cl site, Cl is bonded in a 2-coordinate geometry to two Ta atoms. In the sixth Cl site, Cl is bonded in a 2-coordinate geometry to two equivalent Ta atoms.
