Materials Data on Lu2Si5Ir3 by Materials Project
Lu2Ir3Si5 crystallizes in the orthorhombic Ibam space group. The structure is three-dimensional. Lu3+ is bonded in a 1-coordinate geometry to ten Si4- atoms. There are a spread of Lu–Si bond distances ranging from 2.93–3.27 Å. There are two inequivalent Ir+4.67+ sites. In the first Ir+4.67+ site, Ir+4.67+ is bonded in a distorted hexagonal planar geometry to six Si4- atoms. There are four shorter (2.44 Å) and two longer (2.56 Å) Ir–Si bond lengths. In the second Ir+4.67+ site, Ir+4.67+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are a spread of Ir–Si bond distances ranging from 2.32–2.44 Å. There are three inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 3-coordinate geometry to four equivalent Lu3+, three Ir+4.67+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.53 Å. In the second Si4- site, Si4- is bonded in a 9-coordinate geometry to four equivalent Lu3+, three Ir+4.67+, and two equivalent Si4- atoms. In the third Si4- site, Si4- is bonded in a 4-coordinate geometry to four equivalent Lu3+ and four equivalent Ir+4.67+ atoms.
