The material described by Ag2Mo2O7 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(4), one O(7), and two equivalent O(6) atoms. In the second Mo site, Mo(2) is bonded in a 6-coordinate geometry to one O(1), one O(3), one O(5), one O(6), and two equivalent O(4) atoms. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 6-coordinate geometry to one O(1), one O(2), one O(3), one O(5), and two equivalent O(7) atoms. In the second Ag site, Ag(2) is bonded in a distorted square pyramidal geometry to one O(2), one O(3), one O(4), one O(5), and one O(7) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Mo(1), one Mo(2), and one Ag(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Mo(1), one Ag(1), and one Ag(2) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mo(2), one Ag(1), and one Ag(2) atom. In the fourth O site, O(4) is bonded to one Mo(1), two equivalent Mo(2), and one Ag(2) atom to form distorted edge-sharing OAgMo3 tetrahedra. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Mo(2), one Ag(1), and one Ag(2) atom. In the sixth O site, O(6) is bonded in a 3-coordinate geometry to one Mo(2) and two equivalent Mo(1) atoms. In the seventh O site, O(7) is bonded in a distorted single-bond geometry to one Mo(1), one Ag(2), and two equivalent Ag(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
