Materials Data on CoSn3 by Materials Project
Abstract
CoSn3 crystallizes in the tetragonal I4_1/acd space group. The structure is three-dimensional. Co is bonded in a 9-coordinate geometry to one Co and eight Sn atoms. The Co–Co bond length is 2.72 Å. There are a spread of Co–Sn bond distances ranging from 2.72–2.74 Å. There are two inequivalent Sn sites. In the first Sn site, Sn is bonded in a 5-coordinate geometry to four equivalent Co and three Sn atoms. There are one shorter (2.93 Å) and two longer (3.14 Å) Sn–Sn bond lengths. In the second Sn site, Sn is bonded in a 2-coordinate geometry to two equivalent Co and seven Sn atoms. There are a spread of Sn–Sn bond distances ranging from 3.02–3.27 Å.
