Materials Data on Pu2Si4Tc3 by Materials Project
Pu2Tc3Si4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pu+4.50+ is bonded in a 1-coordinate geometry to four Tc3- atoms. There are a spread of Pu–Tc bond distances ranging from 2.84–3.20 Å. There are two inequivalent Tc3- sites. In the first Tc3- site, Tc3- is bonded in a 12-coordinate geometry to four equivalent Pu+4.50+ and six Si atoms. There are a spread of Tc–Si bond distances ranging from 2.50–2.52 Å. In the second Tc3- site, Tc3- is bonded in a 7-coordinate geometry to two equivalent Pu+4.50+ and five Si atoms. There are a spread of Tc–Si bond distances ranging from 2.42–2.50 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 6-coordinate geometry to four Tc3- atoms. In the second Si site, Si is bonded in a 4-coordinate geometry to four Tc3- atoms.
