Materials Data on NaGe2Pd3 by Materials Project

Abstract

NaPd3Ge2 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Na is bonded in a 10-coordinate geometry to six Pd and four equivalent Ge atoms. There are four shorter (3.14 Å) and two longer (3.26 Å) Na–Pd bond lengths. There are two shorter (3.31 Å) and two longer (3.39 Å) Na–Ge bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd is bonded in a 6-coordinate geometry to two equivalent Na and four equivalent Ge atoms. All Pd–Ge bond lengths are 2.57 Å. In the second Pd site, Pd is bonded in a 6-coordinate geometry to two equivalent Na and four equivalent Ge atoms. There are two shorter (2.50 Å) and two longer (2.58 Å) Pd–Ge bond lengths. Ge is bonded in a 9-coordinate geometry to two equivalent Na, six Pd, and one Ge atom. The Ge–Ge bond length is 2.68 Å.
