Abstract

TaMoS4 is Molybdenite-derived structured and crystallizes in the monoclinic Pm space group. The structure is two-dimensional and consists of one TaMoS4 sheet oriented in the (0, 0, 1) direction. Ta5+ is bonded to six S2- atoms to form distorted TaS6 pentagonal pyramids that share edges with two equivalent TaS6 pentagonal pyramids and edges with four equivalent MoS6 pentagonal pyramids. There are four shorter (2.46 Å) and two longer (2.47 Å) Ta–S bond lengths. Mo3+ is bonded to six S2- atoms to form distorted MoS6 pentagonal pyramids that share edges with two equivalent MoS6 pentagonal pyramids and edges with four equivalent TaS6 pentagonal pyramids. All Mo–S bond lengths are 2.43 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to two equivalent Ta5+ and one Mo3+ atom. In the second S2- site, S2- is bonded in a 3-coordinate geometry to one Ta5+ and two equivalent Mo3+ atoms. In the third S2- site, S2- is bonded in a 3-coordinate geometry to two equivalent Ta5+ and one Mo3+ atom. In the fourth S2- site, S2- is bonded in a 3-coordinate geometry to one Ta5+ and two equivalent Mo3+ atoms.
