The structure described by WAgBi2O8 crystallizes in the monoclinic C2/m space group. W(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form WO6 octahedra that share corners with four equivalent Bi(1)O6 octahedra, corners with four equivalent Bi(2)O6 pentagonal pyramids, and corners with two equivalent Ag(1)O4 trigonal pyramids. The corner-sharing octahedral tilt angles range from 48-50°. Ag(1) is bonded to one O(4), one O(5), and two equivalent O(3) atoms to form distorted AgO4 trigonal pyramids that share corners with two equivalent W(1)O6 octahedra, corners with two equivalent Bi(1)O6 octahedra, corners with two equivalent Bi(2)O6 pentagonal pyramids, and  an edgeedge with one Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 33-63°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with four equivalent W(1)O6 octahedra, corners with two equivalent Ag(1)O4 trigonal pyramids, edges with two equivalent Bi(2)O6 pentagonal pyramids, and  an edgeedge with one Ag(1)O4 trigonal pyramid. The corner-sharing octahedral tilt angles range from 48-50°. In the second Bi site, Bi(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form distorted BiO6 pentagonal pyramids that share corners with four equivalent W(1)O6 octahedra, corners with two equivalent Ag(1)O4 trigonal pyramids, edges with two equivalent Bi(1)O6 octahedra, and  an edgeedge with one Bi(2)O6 pentagonal pyramid. The corner-sharing octahedral tilt angles range from 22-56°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1), one Bi(1), and one Bi(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one W(1) and one Bi(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1), one Ag(1), and one Bi(1) atom. In the fourth O site, O(4) is bonded to one Ag(1), one Bi(1), and two equivalent Bi(2) atoms to form edge-sharing OAgBi3 tetrahedra.
