The structure described by W3AgBr7 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent W sites. In the first W site, W(1) is bonded to one Br(1), one Br(4), one Br(5), one Br(6), and one Br(7) atom to form distorted edge-sharing WBr5 square pyramids. In the second W site, W(2) is bonded to one Br(1), one Br(3), one Br(5), one Br(6), and one Br(7) atom to form distorted edge-sharing WBr5 square pyramids. In the third W site, W(3) is bonded to one Br(1), one Br(2), one Br(5), one Br(6), and one Br(7) atom to form distorted edge-sharing WBr5 square pyramids. Ag(1) is bonded in a distorted trigonal planar geometry to one Br(2), one Br(3), and one Br(4) atom. There are seven inequivalent Br sites. In the first Br site, Br(7) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one W(3) atom. In the second Br site, Br(1) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one W(3) atom. In the third Br site, Br(2) is bonded in a bent 120 degrees geometry to one W(3) and one Ag(1) atom. In the fourth Br site, Br(3) is bonded in a bent 120 degrees geometry to one W(2) and one Ag(1) atom. In the fifth Br site, Br(4) is bonded in a water-like geometry to one W(1) and one Ag(1) atom. In the sixth Br site, Br(5) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one W(3) atom. In the seventh Br site, Br(6) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one W(3) atom. is represented by the CIF file [CIF]
