Title: Materials Data on PmMgSe3 by Materials Project

Abstract

MgPmSe3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Mg2+ is bonded in a 4-coordinate geometry to four Se+1.67- atoms. There are two shorter (2.57 Å) and two longer (2.66 Å) Mg–Se bond lengths. Pm3+ is bonded in a 6-coordinate geometry to seven Se+1.67- atoms. There are a spread of Pm–Se bond distances ranging from 2.90–3.52 Å. There are two inequivalent Se+1.67- sites. In the first Se+1.67- site, Se+1.67- is bonded in a 1-coordinate geometry to one Mg2+ and two equivalent Pm3+ atoms. In the second Se+1.67- site, Se+1.67- is bonded in a 4-coordinate geometry to two equivalent Mg2+ and three equivalent Pm3+ atoms.
