Abstract

Ta4Ga(Te3Se)2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Ta+3.25+ sites. In the first Ta+3.25+ site, Ta+3.25+ is bonded in a 6-coordinate geometry to five Te2- and one Se2- atom. There are a spread of Ta–Te bond distances ranging from 2.74–3.02 Å. The Ta–Se bond length is 2.53 Å. In the second Ta+3.25+ site, Ta+3.25+ is bonded in a 6-coordinate geometry to four Te2- and two equivalent Se2- atoms. There are a spread of Ta–Te bond distances ranging from 2.75–3.04 Å. Both Ta–Se bond lengths are 2.57 Å. Ga3+ is bonded in a tetrahedral geometry to four Te2- atoms. All Ga–Te bond lengths are 2.65 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to three Ta+3.25+ and one Ga3+ atom to form a mixture of edge and corner-sharing TeTa3Ga tetrahedra. In the second Te2- site, Te2- is bonded to three Ta+3.25+ and one Ga3+ atom to form a mixture of edge and corner-sharing TeTa3Ga tetrahedra. In the third Te2- site, Te2- is bonded in a 5-coordinate geometry to three Ta+3.25+ atoms. Se2- is bonded in a 5-coordinate geometry to three Ta+3.25+ atoms.
