Materials Data on Er(ClO2)3 by Materials Project
Er(O2Cl)3 crystallizes in the monoclinic P2/c space group. The structure is two-dimensional and consists of one Er(O2Cl)3 sheet oriented in the (0, 1, 0) direction. Er is bonded in a distorted octahedral geometry to six O atoms. All Er–O bond lengths are 2.25 Å. There are three inequivalent O sites. In the first O site, O is bonded in a bent 150 degrees geometry to one Er and one Cl atom. The O–Cl bond length is 1.57 Å. In the second O site, O is bonded in a bent 120 degrees geometry to one Er and one Cl atom. The O–Cl bond length is 1.58 Å. In the third O site, O is bonded in a bent 150 degrees geometry to one Er and one Cl atom. The O–Cl bond length is 1.57 Å. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a bent 120 degrees geometry to two O atoms. In the second Cl site, Cl is bonded in a water-like geometry to two equivalent O atoms.
