Materials Data on EuBrCl by Materials Project
EuBrCl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu2+ is bonded in a 8-coordinate geometry to four equivalent Br1- and four equivalent Cl1- atoms. There are two shorter (3.15 Å) and two longer (3.25 Å) Eu–Br bond lengths. There are a spread of Eu–Cl bond distances ranging from 2.96–3.08 Å. Br1- is bonded in a 4-coordinate geometry to four equivalent Eu2+ atoms. Cl1- is bonded to four equivalent Eu2+ atoms to form a mixture of distorted corner and edge-sharing ClEu4 tetrahedra.
