The material structure described by ErSbO4 crystallizes in the triclinic P-1 space group. There are two inequivalent Er sites. In the first Er site, Er(1) is bonded in a 8-coordinate geometry to one O(1), one O(2), one O(5), one O(7), two equivalent O(6), and two equivalent O(8) atoms. In the second Er site, Er(2) is bonded in a 7-coordinate geometry to one O(3), one O(4), one O(6), one O(7), one O(8), and two equivalent O(5) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(5), and one O(7) atom to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 41-49°. In the second Sb site, Sb(2) is bonded to one O(1), one O(2), one O(3), one O(4), one O(6), and one O(8) atom to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 41-49°. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Er(1), one Sb(1), and one Sb(2) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Er(1), one Sb(1), and one Sb(2) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Er(2), one Sb(1), and one Sb(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Er(2), one Sb(1), and one Sb(2) atom. In the fifth O site, O(5) is bonded to one Er(1), two equivalent Er(2), and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OEr3Sb tetrahedra. In the sixth O site, O(6) is bonded to one Er(2), two equivalent Er(1), and one Sb(2) atom to form a mixture of distorted edge and corner-sharing OEr3Sb tetrahedra. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one Er(1), one Er(2), and one Sb(1) atom. In the eighth O site, O(8) is bonded in a 4-coordinate geometry to one Er(2), two equivalent Er(1), and one Sb(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
