The compound described by Eu5Sn3H crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Eu sites. In the first Eu site, Eu(1) is bonded to two equivalent Sn(1) and four equivalent Sn(2) atoms to form distorted corner-sharing EuSn6 octahedra. The corner-sharing octahedral tilt angles range from 0-54°. In the second Eu site, Eu(2) is bonded in a distorted single-bond geometry to two equivalent Sn(1), three equivalent Sn(2), and one H(1) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to two equivalent Eu(1) and eight equivalent Eu(2) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Eu(1), six equivalent Eu(2), and one Sn(2) atom. H(1) is bonded in a tetrahedral geometry to four equivalent Eu(2) atoms. is represented by the CIF file [CIF]
