(K)2SrIr is gamma nitrogen-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one potassio-kalium molecule and one SrIr cluster. In the SrIr cluster, Sr(1) is bonded in a single-bond geometry to one Ir(1) atom. The Sr(1)-Ir(1) bond length is 0.32 Å. Ir(1) is bonded in a single-bond geometry to one Sr(1) atom.
