Materials Data on LiCd2HSe2O7 by Materials Project
LiCd2HSe2O7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 1.95–2.00 Å. 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 2.29–2.49 Å. In the second Cd2+ site, Cd2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Cd–O bond distances ranging from 2.30–2.84 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are two inequivalent Se4+ sites. In the first Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.73 Å) and one longer (1.74 Å) Se–O bond length. In the second Se4+ site, Se4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.73 Å) and one longer (1.75 Å) Se–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Li1+, one Cd2+, and one Se4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cd2+, and one Se4+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cd2+, and one Se4+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two Cd2+ and one Se4+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three Cd2+ and one H1+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Cd2+ and one Se4+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cd2+, and one Se4+ atom.
