Materials Data on EuZnIn3 by Materials Project
EuZnIn3 crystallizes in the tetragonal I4mm space group. The structure is three-dimensional. Eu is bonded in a 12-coordinate geometry to four equivalent Zn and twelve In atoms. All Eu–Zn bond lengths are 3.59 Å. There are a spread of Eu–In bond distances ranging from 3.56–3.90 Å. Zn is bonded in a 9-coordinate geometry to four equivalent Eu and five In atoms. There are one shorter (2.59 Å) and four longer (2.78 Å) Zn–In bond lengths. There are two inequivalent In sites. In the first In site, In is bonded in a 2-coordinate geometry to four equivalent Eu, two equivalent Zn, and two equivalent In atoms. Both In–In bond lengths are 3.00 Å. In the second In site, In is bonded in a distorted single-bond geometry to four equivalent Eu, one Zn, and four equivalent In atoms.
