Materials Data on MnCoSi2 by Materials Project
MnCoSi2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Mn4+ is bonded in a 7-coordinate geometry to seven Si4- atoms. There are a spread of Mn–Si bond distances ranging from 2.29–2.51 Å. Co4+ is bonded in a 7-coordinate geometry to seven Si4- atoms. There are a spread of Co–Si bond distances ranging from 2.29–2.52 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 7-coordinate geometry to four equivalent Mn4+ and three equivalent Co4+ atoms. In the second Si4- site, Si4- is bonded in a 5-coordinate geometry to three equivalent Mn4+ and four equivalent Co4+ atoms.
