Re Re Ir Ir Ir
Re2Ir3 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Re2Ir3 clusters. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a single-bond geometry to one Ir(1) atom. The Re(1)-Ir(1) bond length is 0.52 Å. In the second Re site, Re(2) is bonded in a distorted single-bond geometry to one Ir(2) atom. The Re(2)-Ir(2) bond length is 2.28 Å. There are three inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a single-bond geometry to one Re(1) and one Ir(3) atom. The Ir(1)-Ir(3) bond length is 1.76 Å. In the second Ir site, Ir(2) is bonded in a linear geometry to one Re(2) and one Ir(3) atom. The Ir(2)-Ir(3) bond length is 0.45 Å. In the third Ir site, Ir(3) is bonded in a distorted linear geometry to one Ir(1) and one Ir(2) atom.
