Abstract

Ta3(Se4Br3)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Ta3(Se4Br3)2 sheet oriented in the (0, 1, 0) direction. there are three inequivalent Ta+4.67+ sites. In the first Ta+4.67+ site, Ta+4.67+ is bonded in an octahedral geometry to six Br1- atoms. There are a spread of Ta–Br bond distances ranging from 2.50–2.56 Å. In the second Ta+4.67+ site, Ta+4.67+ is bonded to eight Se1- atoms to form distorted face-sharing TaSe8 hexagonal bipyramids. There are a spread of Ta–Se bond distances ranging from 2.61–2.75 Å. In the third Ta+4.67+ site, Ta+4.67+ is bonded to eight Se1- atoms to form distorted face-sharing TaSe8 hexagonal bipyramids. There are a spread of Ta–Se bond distances ranging from 2.61–2.76 Å. There are eight inequivalent Se1- sites. In the first Se1- site, Se1- is bonded in a 2-coordinate geometry to two Ta+4.67+ and one Se1- atom. The Se–Se bond length is 2.39 Å. In the second Se1- site, Se1- is bonded in a 2-coordinate geometry to two Ta+4.67+ and one Se1- atom. The Se–Se bond length is 2.41 Å. In the third Se1- site, Se1- is bonded in a 2-coordinate geometry to two Ta+4.67+, one Se1-, and one Br1- atom.more »« less
