Materials Data on MnSi(AgSe2)2 by Materials Project
Abstract
MnSi(AgSe2)2 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. The structure is three-dimensional. Mn2+ is bonded to four Se2- atoms to form MnSe4 tetrahedra that share corners with four equivalent SiSe4 tetrahedra and corners with eight equivalent AgSe4 tetrahedra. There are a spread of Mn–Se bond distances ranging from 2.50–2.59 Å. Ag1+ is bonded to four Se2- atoms to form AgSe4 tetrahedra that share corners with four equivalent MnSe4 tetrahedra, corners with four equivalent AgSe4 tetrahedra, and corners with four equivalent SiSe4 tetrahedra. There are a spread of Ag–Se bond distances ranging from 2.64–2.70 Å. Si4+ is bonded to four Se2- atoms to form SiSe4 tetrahedra that share corners with four equivalent MnSe4 tetrahedra and corners with eight equivalent AgSe4 tetrahedra. There are a spread of Si–Se bond distances ranging from 2.30–2.33 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to one Mn2+, two equivalent Ag1+, and one Si4+ atom to form corner-sharing SeMnSiAg2 tetrahedra. In the second Se2- site, Se2- is bonded to one Mn2+, two equivalent Ag1+, and one Si4+ atom to form corner-sharing SeMnSiAg2 tetrahedra. In the third Se2- site, Se2- is bonded to one Mn2+, twomore »
