Materials Data on Sc3P2 by Materials Project

Abstract

Sc3P2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Sc2+ sites. In the first Sc2+ site, Sc2+ is bonded to five P3- atoms to form a mixture of face, edge, and corner-sharing ScP5 square pyramids. There are a spread of Sc–P bond distances ranging from 2.61–2.75 Å. In the second Sc2+ site, Sc2+ is bonded to five P3- atoms to form a mixture of face, edge, and corner-sharing ScP5 square pyramids. There are a spread of Sc–P bond distances ranging from 2.60–2.78 Å. In the third Sc2+ site, Sc2+ is bonded to five P3- atoms to form a mixture of distorted edge and corner-sharing ScP5 square pyramids. There are a spread of Sc–P bond distances ranging from 2.65–3.00 Å. There are two inequivalent P3- sites. In the first P3- site, P3- is bonded to seven Sc2+ atoms to form distorted edge-sharing PSc7 pentagonal bipyramids. In the second P3- site, P3- is bonded in a 8-coordinate geometry to eight Sc2+ atoms.
