In the second Ag site, Ag(2) is bonded in a linear geometry to one O(1) and one O(3) atom. In the third Ag site, Ag(3) is bonded in a linear geometry to two equivalent O(1) atoms. In the fourth Ag site, Ag(4) is bonded in a 6-coordinate geometry to six equivalent O(2) atoms. In the fifth Ag site, Ag(5) is bonded in a linear geometry to one O(2) and one O(3) atom. In the sixth Ag site, Ag(6) is bonded in a linear geometry to two equivalent O(3) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in an octahedral geometry to six equivalent O(2) atoms. In the second Bi site, Bi(2) is bonded in an octahedral geometry to three equivalent O(1) and three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(2) is bonded to one Ag(1), one Ag(4), one Ag(5), and one Bi(1) atom to form a mixture of distorted corner and edge-sharing OAg3Bi trigonal pyramids. In the second O site, O(3) is bonded to one Ag(2), one Ag(5), one Ag(6), and one Bi(2) atom to form distorted corner-sharing OAg3Bi tetrahedra. In the third O site, O(1) is bonded to one Ag(1), one Ag(2), one Ag(3), and one Bi(2) atom to form corner-sharing OAg3Bi tetrahedra.
