MnIr2Pd crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two MnIr2Pd clusters. Mn(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Pd(1) atom. The Mn(1)-Ir(1) bond length is 1.64 Å. The Mn(1)-Pd(1) bond length is 1.52 Å. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 2-coordinate geometry to one Mn(1) and one Ir(2) atom. The Ir(1)-Ir(2) bond length is 1.11 Å. In the second Ir site, Ir(2) is bonded in a distorted single-bond geometry to one Ir(1) atom. Pd(1) is bonded in a distorted single-bond geometry to one Mn(1) atom.
