Materials Data on LaGe2IrRu by Materials Project

Abstract

LaRuIrGe2 crystallizes in the tetragonal I-4m2 space group. The structure is three-dimensional. La is bonded in a 8-coordinate geometry to four equivalent Ru, four equivalent Ir, and eight equivalent Ge atoms. All La–Ru bond lengths are 3.37 Å. All La–Ir bond lengths are 3.37 Å. All La–Ge bond lengths are 3.32 Å. Ru is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Ge atoms. All Ru–Ge bond lengths are 2.48 Å. Ir is bonded in a 4-coordinate geometry to four equivalent La and four equivalent Ge atoms. All Ir–Ge bond lengths are 2.48 Å. Ge is bonded in a 9-coordinate geometry to four equivalent La, two equivalent Ru, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.71 Å.
