MoAg2Te4O12 crystallizes in the monoclinic C2/c space group. Mo(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted MoO6 octahedra that share corners with two equivalent Te(1)O5 square pyramids. Ag(1) is bonded in a 7-coordinate geometry to one O(2), two equivalent O(3), two equivalent O(5), and two equivalent O(6) atoms. There are two inequivalent Te sites. In the first Te site, Te(1) is bonded to one O(2), one O(5), one O(6), and two equivalent O(3) atoms to form distorted TeO5 square pyramids that share  a cornercorner with one Mo(1)O6 octahedra and  an edgeedge with one Te(1)O5 square pyramid. The corner-sharing octahedral tilt angles are 51°. In the second Te site, Te(2) is bonded in a 3-coordinate geometry to one O(1), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(2) is bonded in a trigonal planar geometry to one Mo(1), one Ag(1), and one Te(1) atom. In the second O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Ag(1) and two equivalent Te(1) atoms. In the third O site, O(4) is bonded in a single-bond geometry to one Mo(1) atom. In the fourth O site, O(5) is bonded in a distorted bent 120 degrees geometry to two equivalent Ag(1), one Te(1), and one Te(2) atom. In the fifth O site, O(6) is bonded to two equivalent Ag(1), one Te(1), and one Te(2) atom to form distorted corner-sharing OAg2Te2 trigonal pyramids. In the sixth O site, O(1) is bonded in a 2-coordinate geometry to one Mo(1) and one Te(2) atom.
