Abstract

Yb4O13Cl2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Yb sites. In the first Yb site, Yb is bonded in a 6-coordinate geometry to eight O atoms. There are a spread of Yb–O bond distances ranging from 2.31–2.71 Å. In the second Yb site, Yb is bonded in a 7-coordinate geometry to eight O atoms. There are a spread of Yb–O bond distances ranging from 2.32–2.83 Å. In the third Yb site, Yb is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Yb–O bond distances ranging from 2.29–2.48 Å. In the fourth Yb site, Yb is bonded in a 5-coordinate geometry to seven O atoms. There are a spread of Yb–O bond distances ranging from 2.24–2.80 Å. There are thirteen inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two Yb and one O atom. The O–O bond length is 1.36 Å. In the second O site, O is bonded in a T-shaped geometry to two Yb and one Cl atom. The O–Cl bond length is 1.67 Å. In the third O site, O is bonded in a 3-coordinate geometry to two Yb and one O atom. In the fourth O site, O is bonded in a distorted L-shaped geometry to one Yb and one O atom. The O–O bond length is 1.27 Å. In the fifth O site, O is bonded in a distorted see-saw-like geometry to three Yb and one O atom. The O–O bond length is 1.40 Å. In the sixth O site, O is bonded to three Yb and one Cl atom to form distorted corner-sharing OYb3Cl trigonal pyramids. The O–Cl bond length is 1.70 Å. In the seventh O site, O is bonded in a 4-coordinate geometry to three Yb and one O atom. The O–O bond length is 1.44 Å. In the eighth O site, O is bonded to three Yb and one O atom to form distorted corner-sharing OYb3O trigonal pyramids. The O–O bond length is 1.51 Å. In the ninth O site, O is bonded in a 3-coordinate geometry to two Yb and one O atom. The O–O bond length is 1.41 Å. In the tenth O site, O is bonded in a 3-coordinate geometry to two Yb and one O atom. In the eleventh O site, O is bonded in a 4-coordinate geometry to three Yb and one O atom. In the twelfth O site, O is bonded in a 5-coordinate geometry to three Yb and two O atoms. In the thirteenth O site, O is bonded in a distorted T-shaped geometry to two Yb and one O atom. There are two inequivalent Cl sites. In the first Cl site, Cl is bonded in a single-bond geometry to one O atom. In the second Cl site, Cl is bonded in a single-bond geometry to one O atom.
