Materials Data on TmCd3 by Materials Project
TmCd3 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 10-coordinate geometry to twelve Cd atoms. There are a spread of Tm–Cd bond distances ranging from 3.18–3.63 Å. There are two inequivalent Cd sites. In the first Cd site, Cd is bonded in a 12-coordinate geometry to four equivalent Tm and eight equivalent Cd atoms. There are a spread of Cd–Cd bond distances ranging from 3.01–3.33 Å. In the second Cd site, Cd is bonded in a 11-coordinate geometry to four equivalent Tm and seven Cd atoms. There are one shorter (3.10 Å) and two longer (3.19 Å) Cd–Cd bond lengths.
