Materials Data on Gd2Cl3 by Materials Project
Gd2Cl3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Gd sites. In the first Gd site, Gd is bonded in a 5-coordinate geometry to five Cl atoms. There are a spread of Gd–Cl bond distances ranging from 2.80–3.08 Å. In the second Gd site, Gd is bonded in a distorted pentagonal planar geometry to five Cl atoms. There are a spread of Gd–Cl bond distances ranging from 2.72–2.85 Å. There are three inequivalent Cl sites. In the first Cl site, Cl is bonded in a trigonal non-coplanar geometry to three equivalent Gd atoms. In the second Cl site, Cl is bonded in a rectangular see-saw-like geometry to four Gd atoms. In the third Cl site, Cl is bonded in a distorted T-shaped geometry to three Gd atoms.
