The crystal structure described by EuF3 crystallizes in the orthorhombic Pnma space group. Eu(1) is bonded in a 9-coordinate geometry to three equivalent F(2) and six equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(2) is bonded in a trigonal planar geometry to three equivalent Eu(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to three equivalent Eu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
