Materials Data on La7Ru3 by Materials Project

Abstract

La7Ru3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are four inequivalent La sites. In the first La site, La is bonded to four Ru atoms to form a mixture of distorted corner and edge-sharing LaRu4 tetrahedra. There are a spread of La–Ru bond distances ranging from 3.04–3.11 Å. In the second La site, La is bonded in a 3-coordinate geometry to three equivalent Ru atoms. There are a spread of La–Ru bond distances ranging from 2.92–3.18 Å. In the third La site, La is bonded in a distorted bent 150 degrees geometry to two equivalent Ru atoms. There are one shorter (2.75 Å) and one longer (2.88 Å) La–Ru bond lengths. In the fourth La site, La is bonded in a 2-coordinate geometry to three Ru atoms. There are a spread of La–Ru bond distances ranging from 2.76–3.47 Å. There are two inequivalent Ru sites. In the first Ru site, Ru is bonded in a 7-coordinate geometry to seven La atoms. In the second Ru site, Ru is bonded in a 6-coordinate geometry to eight La atoms.
