Tl Tl P Ir
IrTlTlP crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrTl clusters and two TlP clusters. In each IrTl cluster, Ir(1) is bonded in a distorted single-bond geometry to one Tl(1) atom. The Ir(1)-Tl(1) bond length is 2.09 Å. Tl(1) is bonded in a single-bond geometry to one Ir(1) atom. In each TlP cluster, Tl(2) is bonded in a single-bond geometry to one P(1) atom. The Tl(2)-P(1) bond length is 2.44 Å. P(1) is bonded in a 1-coordinate geometry to one Tl(2) atom.
