The structure described by Cs2MnTe2 crystallizes in the triclinic P1 space group. There are four inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to one Mn(1), one Mn(2), one Te(1), one Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. In the second Cs site, Cs(2) is bonded in a 8-coordinate geometry to one Mn(1), one Mn(2), one Te(3), one Te(4), two equivalent Te(1), and two equivalent Te(2) atoms. In the third Cs site, Cs(3) is bonded in a 8-coordinate geometry to one Mn(1), one Mn(2), one Te(1), one Te(2), two equivalent Te(3), and two equivalent Te(4) atoms. In the fourth Cs site, Cs(4) is bonded in a 8-coordinate geometry to one Mn(1), one Mn(2), one Te(3), one Te(4), two equivalent Te(1), and two equivalent Te(2) atoms. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one Cs(1), one Cs(2), one Cs(3), one Cs(4), one Te(1), one Te(2), one Te(3), and one Te(4) atom to form distorted face-sharing MnCs4Te4 tetrahedra. In the second Mn site, Mn(2) is bonded to one Cs(1), one Cs(2), one Cs(3), one Cs(4), one Te(1), one Te(2), one Te(3), and one Te(4) atom to form distorted face-sharing MnCs4Te4 tetrahedra. There are four inequivalent Te sites. In the first Te site, Te(1) is bonded in a 8-coordinate geometry to one Cs(1), one Cs(3), two equivalent Cs(2), two equivalent Cs(4), one Mn(1), and one Mn(2) atom. In the second Te site, Te(2) is bonded in a 8-coordinate geometry to one Cs(1), one Cs(3), two equivalent Cs(2), two equivalent Cs(4), one Mn(1), and one Mn(2) atom. In the third Te site, Te(3) is bonded in a 8-coordinate geometry to one Cs(2), one Cs(4), two equivalent Cs(1), two equivalent Cs(3), one Mn(1), and one Mn(2) atom. In the fourth Te site, Te(4) is bonded in a 8-coordinate geometry to one Cs(2), one Cs(4), two equivalent Cs(1), two equivalent Cs(3), one Mn(1), and one Mn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
