Materials Data on LaIn5Co by Materials Project

Abstract

LaCoIn5 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. La is bonded to twelve In atoms to form a mixture of face and corner-sharing LaIn12 cuboctahedra. There are four shorter (3.30 Å) and eight longer (3.35 Å) La–In bond lengths. Co is bonded in a body-centered cubic geometry to eight equivalent In atoms. All Co–In bond lengths are 2.75 Å. There are two inequivalent In sites. In the first In site, In is bonded in a distorted square co-planar geometry to four equivalent La and eight equivalent In atoms. All In–In bond lengths are 3.35 Å. In the second In site, In is bonded in a 4-coordinate geometry to two equivalent La, two equivalent Co, and seven In atoms. There are one shorter (2.89 Å) and four longer (3.30 Å) In–In bond lengths.
