Na Ir Ir W
NaWIr2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 1-coordinate geometry to one W(1), one Ir(2), and two equivalent Ir(1) atoms. The Na(1)-W(1) bond length is 2.17 Å. The Na(1)-Ir(2) bond length is 1.57 Å. There is one shorter (3.12 Å) and one longer (3.18 Å) Na(1)-Ir(1) bond length. W(1) is bonded in a 1-coordinate geometry to one Na(1) and two equivalent Ir(1) atoms. There is one shorter (2.34 Å) and one longer (2.80 Å) W(1)-Ir(1) bond length. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 7-coordinate geometry to two equivalent Na(1), two equivalent W(1), one Ir(2), and two equivalent Ir(1) atoms. The Ir(1)-Ir(2) bond length is 2.23 Å. Both Ir(1)-Ir(1) bond lengths are 2.75 Å. In the second Ir site, Ir(2) is bonded in a single-bond geometry to one Na(1) and one Ir(1) atom.
