Materials Data on LaY3 by Materials Project

Abstract

LaY3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. La is bonded to twelve equivalent Y atoms to form LaY12 cuboctahedra that share corners with twelve equivalent LaY12 cuboctahedra, edges with twenty-four equivalent YLa4Y8 cuboctahedra, faces with six equivalent LaY12 cuboctahedra, and faces with twelve equivalent YLa4Y8 cuboctahedra. All La–Y bond lengths are 3.62 Å. Y is bonded to four equivalent La and eight equivalent Y atoms to form YLa4Y8 cuboctahedra that share corners with twelve equivalent YLa4Y8 cuboctahedra, edges with eight equivalent LaY12 cuboctahedra, edges with sixteen equivalent YLa4Y8 cuboctahedra, faces with four equivalent LaY12 cuboctahedra, and faces with fourteen equivalent YLa4Y8 cuboctahedra. All Y–Y bond lengths are 3.62 Å.
