The crystal structure described by Ca4N4Te crystallizes in the orthorhombic Pnma space group. There are four inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 6-coordinate geometry to one N(4), two equivalent N(2), two equivalent N(3), and one Te(1) atom. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to one N(1), two equivalent N(2), and three equivalent N(3) atoms. In the third Ca site, Ca(3) is bonded in a 7-coordinate geometry to two equivalent N(1), two equivalent N(4), and three equivalent Te(1) atoms. In the fourth Ca site, Ca(4) is bonded in a 7-coordinate geometry to one N(2), two equivalent N(1), two equivalent N(4), and two equivalent Te(1) atoms. There are four inequivalent N sites. In the first N site, N(4) is bonded in a 6-coordinate geometry to one Ca(1), two equivalent Ca(3), two equivalent Ca(4), and one N(1) atom. In the second N site, N(1) is bonded in a 6-coordinate geometry to one Ca(2), two equivalent Ca(3), two equivalent Ca(4), and one N(4) atom. In the third N site, N(2) is bonded in a 6-coordinate geometry to one Ca(4), two equivalent Ca(1), two equivalent Ca(2), and one N(3) atom. In the fourth N site, N(3) is bonded in a 6-coordinate geometry to two equivalent Ca(1), three equivalent Ca(2), and one N(2) atom. Te(1) is bonded in a 6-coordinate geometry to one Ca(1), two equivalent Ca(4), and three equivalent Ca(3) atoms. is represented by the CIF file [CIF]
