The material described by Co2Ni2Te5 crystallizes in the triclinic P-1 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to one Ni(1), one Ni(2), one Te(1), one Te(2), one Te(3), one Te(5), and two equivalent Te(4) atoms. In the second Co site, Co(2) is bonded in a 7-coordinate geometry to one Ni(2), one Te(3), one Te(5), two equivalent Te(1), and two equivalent Te(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 7-coordinate geometry to one Co(1), one Te(2), one Te(5), two equivalent Te(3), and two equivalent Te(4) atoms. In the second Ni site, Ni(2) is bonded in a 8-coordinate geometry to one Co(1), one Co(2), one Te(2), one Te(3), one Te(4), one Te(5), and two equivalent Te(1) atoms. There are five inequivalent Te sites. In the first Te site, Te(1) is bonded in a 5-coordinate geometry to one Co(1), two equivalent Co(2), and two equivalent Ni(2) atoms. In the second Te site, Te(2) is bonded in a 5-coordinate geometry to one Co(1), two equivalent Co(2), one Ni(1), and one Ni(2) atom. In the third Te site, Te(3) is bonded in a 5-coordinate geometry to one Co(1), one Co(2), one Ni(2), and two equivalent Ni(1) atoms. In the fourth Te site, Te(4) is bonded in a 5-coordinate geometry to two equivalent Co(1), one Ni(2), and two equivalent Ni(1) atoms. In the fifth Te site, Te(5) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one Ni(1), and one Ni(2) atom. is represented by the CIF file [CIF]
