KIrP2 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 1-coordinate geometry to one P(2) and three equivalent P(1) atoms. The K(1)-P(2) bond length is 2.68 Å. There is one shorter (3.37 Å) and two longer (3.77 Å) K(1)-P(1) bond lengths. Ir(1) is bonded in a 2-coordinate geometry to one P(2) and four equivalent P(1) atoms. The Ir(1)-P(2) bond length is 1.99 Å. There are a spread of Ir(1)-P(1) bond distances ranging from 1.99-3.12 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a 8-coordinate geometry to three equivalent K(1), four equivalent Ir(1), and one P(2) atom. The P(1)-P(2) bond length is 2.12 Å. In the second P site, P(2) is bonded in a 2-coordinate geometry to one K(1), one Ir(1), and one P(1) atom.
