Materials Data on Cd2B2O5 by Materials Project
Cd2B2O5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cd–O bond distances ranging from 2.23–2.56 Å. In the second Cd2+ site, Cd2+ is bonded to six O2- atoms to form edge-sharing CdO6 octahedra. There are a spread of Cd–O bond distances ranging from 2.26–2.43 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.37 Å) and one longer (1.43 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.36–1.42 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Cd2+ and two B3+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three equivalent Cd2+ and one B3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Cd2+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Cd2+ and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Cd2+ and one B3+ atom.
