Ag Ag Ir W
WIrAg2 crystallizes in the monoclinic Cm space group. W(1) is bonded in a single-bond geometry to one Ag(1) and one Ag(2) atom. The W(1)-Ag(1) bond length is 0.80 Å. The W(1)-Ag(2) bond length is 2.79 Å. Ir(1) is bonded to six equivalent Ir(1), one Ag(1), and one Ag(2) atom to form a mixture of edge and corner-sharing IrAg2Ir6 hexagonal bipyramids. All Ir(1)-Ir(1) bond lengths are 2.78 Å. The Ir(1)-Ag(1) bond length is 3.14 Å. The Ir(1)-Ag(2) bond length is 3.14 Å. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one W(1) and one Ir(1) atom. In the second Ag site, Ag(2) is bonded in a 8-coordinate geometry to one W(1), one Ir(1), and six equivalent Ag(2) atoms. All Ag(2)-Ag(2) bond lengths are 2.78 Å.
