Materials Data on Sc2Sb by Materials Project
Sc2Sb crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. there are two inequivalent Sc sites. In the first Sc site, Sc is bonded in a 12-coordinate geometry to four equivalent Sb atoms. All Sc–Sb bond lengths are 3.05 Å. In the second Sc site, Sc is bonded to five equivalent Sb atoms to form a mixture of distorted edge and corner-sharing ScSb5 square pyramids. There are one shorter (2.95 Å) and four longer (3.03 Å) Sc–Sb bond lengths. Sb is bonded in a 9-coordinate geometry to nine Sc atoms.
