Materials Data on KMnRu by Materials Project
KMnRu is half-Heusler structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional. K is bonded to six equivalent Mn and four equivalent Ru atoms to form a mixture of distorted corner and face-sharing KMn6Ru4 tetrahedra. All K–Mn bond lengths are 3.27 Å. All K–Ru bond lengths are 2.83 Å. Mn is bonded in a 4-coordinate geometry to six equivalent K and four equivalent Ru atoms. All Mn–Ru bond lengths are 2.83 Å. Ru is bonded in a body-centered cubic geometry to four equivalent K and four equivalent Mn atoms.
