Title: Materials Data on Ta2FeS4 by Materials Project

Abstract

Ta2FeS4 crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Ta2FeS4 sheet oriented in the (0, 0, 1) direction. Ta3+ is bonded to six S2- atoms to form distorted TaS6 pentagonal pyramids that share corners with six equivalent FeS6 octahedra, edges with six equivalent TaS6 pentagonal pyramids, and a faceface with one FeS6 octahedra. The corner-sharing octahedral tilt angles are 48°. There are three shorter (2.47 Å) and three longer (2.51 Å) Ta–S bond lengths. Fe2+ is bonded to six equivalent S2- atoms to form FeS6 octahedra that share corners with twelve equivalent TaS6 pentagonal pyramids, edges with six equivalent FeS6 octahedra, and faces with two equivalent TaS6 pentagonal pyramids. All Fe–S bond lengths are 2.28 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 6-coordinate geometry to three equivalent Ta3+ and three equivalent Fe2+ atoms. In the second S2- site, S2- is bonded in a 3-coordinate geometry to three equivalent Ta3+ atoms.
