Mg Ag Ir Ir
AgMg(Ir)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one iridium molecule and one AgMg cluster. In the AgMg cluster, Mg(1) is bonded in a 1-coordinate geometry to one Ag(1) atom. The Mg(1)-Ag(1) bond length is 1.23 Å. Ag(1) is bonded in a distorted single-bond geometry to one Mg(1) atom.
