Materials Data on SmSiRu by Materials Project
SmRuSi is Matlockite structured and crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm2+ is bonded in a 5-coordinate geometry to five equivalent Si4- atoms. There are four shorter (3.14 Å) and one longer (3.39 Å) Sm–Si bond lengths. Ru2+ is bonded to four equivalent Si4- atoms to form a mixture of edge and corner-sharing RuSi4 tetrahedra. All Ru–Si bond lengths are 2.44 Å. Si4- is bonded in a 9-coordinate geometry to five equivalent Sm2+ and four equivalent Ru2+ atoms.
