Materials Data on Er2SbO2 by Materials Project
Er2SbO2 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. Er3+ is bonded in a 4-coordinate geometry to four equivalent Sb2- and four equivalent O2- atoms. There are two shorter (3.41 Å) and two longer (3.60 Å) Er–Sb bond lengths. There are one shorter (2.20 Å) and three longer (2.21 Å) Er–O bond lengths. Sb2- is bonded in a body-centered cubic geometry to eight equivalent Er3+ atoms. O2- is bonded to four equivalent Er3+ atoms to form a mixture of corner and edge-sharing OEr4 tetrahedra.
