KEr(SO5)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of K–O bond distances ranging from 2.64–3.32 Å. Er is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Er–O bond distances ranging from 2.25–2.48 Å. There are two inequivalent S sites. In the first S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.45–1.52 Å. In the second S site, S is bonded in a tetrahedral geometry to four O atoms. There are a spread of S–O bond distances ranging from 1.46–1.51 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to two equivalent K and one S atom. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one K and one Er atom. In the third O site, O is bonded in a distorted single-bond geometry to one K and one S atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Er and one S atom. In the fifth O site, O is bonded in a distorted single-bond geometry to one K, one Er, and one S atom. In the sixth O site, O is bonded in a distorted bent 150 degrees geometry to one K, one Er, and one S atom. In the seventh O site, O is bonded in a 1-coordinate geometry to one K, one Er, and one S atom. In the eighth O site, O is bonded in a bent 120 degrees geometry to one K and one Er atom. In the ninth O site, O is bonded in a distorted bent 150 degrees geometry to one Er and one S atom. In the tenth O site, O is bonded in a distorted bent 150 degrees geometry to one Er and one S atom.
