K Ir Ir Pt
KIr2Pt crystallizes in the monoclinic Cm space group. K(1) is bonded in a 12-coordinate geometry to four equivalent K(1), four equivalent Ir(2), and four equivalent Pt(1) atoms. All K(1)-K(1) bond lengths are 2.82 Å. There are a spread of K(1)-Ir(2) bond distances ranging from 2.52-3.05 Å. There are a spread of K(1)-Pt(1) bond distances ranging from 3.04-3.49 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 12-coordinate geometry to four equivalent Ir(1), four equivalent Ir(2), and four equivalent Pt(1) atoms. All Ir(1)-Ir(1) bond lengths are 2.82 Å. There are a spread of Ir(1)-Ir(2) bond distances ranging from 2.88-3.35 Å. There are a spread of Ir(1)-Pt(1) bond distances ranging from 2.81-3.29 Å. In the second Ir site, Ir(2) is bonded in a 3-coordinate geometry to four equivalent K(1) and four equivalent Ir(1) atoms. Pt(1) is bonded in a 12-coordinate geometry to four equivalent K(1), four equivalent Ir(1), and four equivalent Pt(1) atoms. All Pt(1)-Pt(1) bond lengths are 2.82 Å.
