Materials Data on Eu(PRu)2 by Materials Project

Eu(RuP)2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Eu2+ is bonded in a body-centered cubic geometry to eight equivalent P3- atoms. All Eu–P bond lengths are 3.26 Å. Ru2+ is bonded to four equivalent P3- atoms to form a mixture of edge and corner-sharing RuP4 tetrahedra. All Ru–P bond lengths are 2.33 Å. P3- is bonded in a 8-coordinate geometry to four equivalent Eu2+ and four equivalent Ru2+ atoms.

Materials Data on Eu(P3Ru)4 by Materials Project

EuRu4P12 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Eu2+ is bonded to twelve equivalent P1- atoms to form EuP12 cuboctahedra that share faces with eight equivalent RuP6 octahedra. All Eu–P bond lengths are 3.13 Å. Ru+2.50+ is bonded to six equivalent P1- atoms to form RuP6 octahedra that share corners with six equivalent RuP6 octahedra and faces with two equivalent EuP12 cuboctahedra. The corner-sharing octahedral tilt angles are 63°. All Ru–P bond lengths are 2.37 Å. P1- is bonded in a 5-coordinate geometry to one Eu2+, two equivalent Ru+2.50+, and two equivalent P1- atoms. There are one shorter (2.29 Å) and one longer (2.32 Å) P–P bond lengths.
