Materials Data on TiGeIr by Materials Project

Abstract

TiIrGe crystallizes in the orthorhombic Ima2 space group. The structure is three-dimensional. there are three inequivalent Ti sites. In the first Ti site, Ti is bonded in a 11-coordinate geometry to six Ir and five Ge atoms. There are a spread of Ti–Ir bond distances ranging from 2.78–2.92 Å. There are a spread of Ti–Ge bond distances ranging from 2.71–2.99 Å. In the second Ti site, Ti is bonded in a 5-coordinate geometry to four Ir and six Ge atoms. There are two shorter (2.93 Å) and two longer (3.16 Å) Ti–Ir bond lengths. There are a spread of Ti–Ge bond distances ranging from 2.61–3.20 Å. In the third Ti site, Ti is bonded in a 9-coordinate geometry to four Ir and five Ge atoms. There are two shorter (2.83 Å) and two longer (2.86 Å) Ti–Ir bond lengths. There are a spread of Ti–Ge bond distances ranging from 2.69–2.81 Å. There are two inequivalent Ir sites. In the first Ir site, Ir is bonded in a 8-coordinate geometry to four Ti, one Ir, and four Ge atoms. The Ir–Ir bond length is 2.89 Å. There are a spread of Ir–Ge bond distances ranging from 2.52–2.54 Å. In the second Ir site, Ir is bonded in a 12-coordinate geometry to six Ti, two equivalent Ir, and four Ge atoms. There are two shorter (2.50 Å) and two longer (2.55 Å) Ir–Ge bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to six Ti and three Ir atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to four Ti and six Ir atoms.
