Materials Data on Y5(Ge5Ir2)2 by Materials Project
Abstract
Y5(Ir2Ge5)2 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. there are three inequivalent Y sites. In the first Y site, Y is bonded in a 8-coordinate geometry to four equivalent Ir and twelve Ge atoms. All Y–Ir bond lengths are 3.22 Å. There are eight shorter (2.99 Å) and four longer (3.36 Å) Y–Ge bond lengths. In the second Y site, Y is bonded to four equivalent Ir and eight Ge atoms to form face-sharing YGe8Ir4 cuboctahedra. All Y–Ir bond lengths are 3.13 Å. There are a spread of Y–Ge bond distances ranging from 2.95–3.08 Å. In the third Y site, Y is bonded in a 8-coordinate geometry to four equivalent Ir and ten Ge atoms. All Y–Ir bond lengths are 3.34 Å. There are a spread of Y–Ge bond distances ranging from 3.29–3.38 Å. Ir is bonded in a 10-coordinate geometry to five Y and five Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.47–2.57 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Y, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.45 Å. Inmore »
