Abstract

MgSmSe3 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 (2.59 Å) and two longer (2.64 Å) Mg–Se bond lengths. Sm3+ is bonded to six Se+1.67- atoms to form a mixture of distorted edge and face-sharing SmSe6 pentagonal pyramids. There are a spread of Sm–Se bond distances ranging from 2.85–3.00 Å. There are two inequivalent Se+1.67- sites. In the first Se+1.67- site, Se+1.67- is bonded in a 3-coordinate geometry to one Mg2+ and two equivalent Sm3+ atoms. In the second Se+1.67- site, Se+1.67- is bonded to two equivalent Mg2+ and two equivalent Sm3+ atoms to form distorted edge-sharing SeSm2Mg2 trigonal pyramids.
