Materials Data on SmAsRuO by Materials Project
SmRuAsO crystallizes in the tetragonal P4/nmm space group. The structure is three-dimensional. Sm3+ is bonded in a 4-coordinate geometry to four equivalent As3- and four equivalent O2- atoms. All Sm–As bond lengths are 3.36 Å. All Sm–O bond lengths are 2.33 Å. Ru2+ is bonded to four equivalent As3- atoms to form a mixture of edge and corner-sharing RuAs4 tetrahedra. All Ru–As bond lengths are 2.44 Å. As3- is bonded in a 8-coordinate geometry to four equivalent Sm3+ and four equivalent Ru2+ atoms. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of distorted edge and corner-sharing OSm4 tetrahedra.
