Title: Materials Data on Ta20Pd9S50 by Materials Project

Abstract

Ta20Pd9S50 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are six inequivalent Ta+4.10+ sites. In the first Ta+4.10+ site, Ta+4.10+ is bonded to seven S2- atoms to form distorted TaS7 pentagonal bipyramids that share edges with two equivalent TaS7 pentagonal bipyramids, edges with two equivalent TaS6 pentagonal pyramids, and faces with two equivalent TaS7 pentagonal bipyramids. There are a spread of Ta–S bond distances ranging from 2.48–2.68 Å. In the second Ta+4.10+ site, Ta+4.10+ is bonded to seven S2- atoms to form distorted TaS7 pentagonal bipyramids that share edges with two TaS7 pentagonal bipyramids, edges with two TaS6 pentagonal pyramids, and faces with two TaS7 pentagonal bipyramids. There are a spread of Ta–S bond distances ranging from 2.48–2.73 Å. In the third Ta+4.10+ site, Ta+4.10+ is bonded to seven S2- atoms to form distorted TaS7 pentagonal bipyramids that share edges with two TaS7 pentagonal bipyramids, edges with two TaS6 pentagonal pyramids, and faces with two TaS7 pentagonal bipyramids.

There are two shorter (2.47 Å) and two longer (2.49 Å) Pd–S bond lengths. There are fifteen inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to three Ta+4.10+ atoms. In the second S2- site, S2- is bonded in a 3-coordinate geometry to three Ta+4.10+ atoms.
