Materials Data on DyGe2Ir by Materials Project

DyIrGe2 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. there are two inequivalent Dy sites. In the first Dy site, Dy is bonded in a 8-coordinate geometry to four equivalent Ir and ten Ge atoms. All Dy–Ir bond lengths are 3.18 Å. There are a spread of Dy–Ge bond distances ranging from 3.27–3.40 Å. In the second Dy site, Dy is bonded in a 8-coordinate geometry to six equivalent Ir and nine Ge atoms. There are four shorter (3.24 Å) and two longer (3.27 Å) Dy–Ir bond lengths. There are a spread of Dy–Ge bond distances ranging from 2.95–3.48 Å. Ir is bonded in a 10-coordinate geometry to five Dy and five Ge atoms. There are a spread of Ir–Ge bond distances ranging from 2.47–2.62 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 2-coordinate geometry to five Dy and two equivalent Ir atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to six Dy, two equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.48 Å. In the third Ge site, Ge is bonded in a 8-coordinate geometry to four Dy, three equivalent Ir, and one Ge atom. The Ge–Ge bond length is 2.72 Å.
