The material described by V2FeAgO7 crystallizes in the triclinic P-1 space group. There are two inequivalent V sites. In the first V site, V(1) is bonded to one O(1), one O(4), one O(6), and one O(7) atom to form VO4 tetrahedra that share corners with three equivalent Fe(1)O6 octahedra and  a cornercorner with one V(2)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 29-59°. In the second V site, V(2) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form VO4 tetrahedra that share corners with three equivalent Fe(1)O6 octahedra and  a cornercorner with one V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 16-41°. Fe(1) is bonded to one O(2), one O(3), one O(5), one O(6), and two equivalent O(1) atoms to form FeO6 octahedra that share corners with three equivalent V(1)O4 tetrahedra, corners with three equivalent V(2)O4 tetrahedra, and  an edgeedge with one Fe(1)O6 octahedra. Ag(1) is bonded in a 2-coordinate geometry to one O(2) 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 V(1) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to one V(2), one Fe(1), and one Ag(1) atom. In the third O site, O(3) is bonded in a linear geometry to one V(2) and one Fe(1) atom. In the fourth O site, O(4) is bonded in a distorted linear geometry to one V(1) and one V(2) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one V(2) and one Fe(1) atom. In the sixth O site, O(6) is bonded in a distorted bent 150 degrees geometry to one V(1) and one Fe(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one V(1) and one Ag(1) atom. is represented by the CIF card [CIF]
