Materials Data on Eu(SbPd)2 by Materials Project

EuPd2Sb2 crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Eu2+ is bonded in a 8-coordinate geometry to eight Sb3- atoms. There are four shorter (3.52 Å) and four longer (3.63 Å) Eu–Sb bond lengths. There are two inequivalent Pd2+ sites. In the first Pd2+ site, Pd2+ is bonded to four equivalent Sb3- atoms to form a mixture of edge and corner-sharing PdSb4 tetrahedra. All Pd–Sb bond lengths are 2.70 Å. In the second Pd2+ site, Pd2+ is bonded in a 5-coordinate geometry to five Sb3- atoms. There are one shorter (2.62 Å) and four longer (2.71 Å) Pd–Sb bond lengths. There are two inequivalent Sb3- sites. In the first Sb3- site, Sb3- is bonded in a 4-coordinate geometry to four equivalent Eu2+ and four equivalent Pd2+ atoms. In the second Sb3- site, Sb3- is bonded in a 9-coordinate geometry to four equivalent Eu2+ and five Pd2+ atoms.
