Materials Data on Eu(AlCl4)2 by Materials Project
Abstract
Eu(AlCl4)2 crystallizes in the monoclinic P2/c space group. The structure is two-dimensional and consists of one Eu(AlCl4)2 sheet oriented in the (1, 0, 0) direction. Eu2+ is bonded in a 8-coordinate geometry to eight Cl1- atoms. There are a spread of Eu–Cl bond distances ranging from 3.05–3.08 Å. Al3+ is bonded in a tetrahedral geometry to four Cl1- atoms. All Al–Cl bond lengths are 2.16 Å. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a distorted L-shaped geometry to one Eu2+ and one Al3+ atom. In the second Cl1- site, Cl1- is bonded in a distorted bent 120 degrees geometry to one Eu2+ and one Al3+ atom. In the third Cl1- site, Cl1- is bonded in a distorted L-shaped geometry to one Eu2+ and one Al3+ atom. In the fourth Cl1- site, Cl1- is bonded in a 1-coordinate geometry to one Eu2+ and one Al3+ atom.
