Materials Data on Cd(HO)2 by Materials Project
Cd(OH)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are two inequivalent Cd2+ sites. In the first Cd2+ site, Cd2+ is bonded to six O2- atoms to form a mixture of edge, corner, and face-sharing CdO6 octahedra. The corner-sharing octahedra tilt angles range from 31–64°. There are a spread of Cd–O bond distances ranging from 2.29–2.51 Å. In the second Cd2+ site, Cd2+ is bonded to six O2- atoms to form a mixture of edge, corner, and face-sharing CdO6 octahedra. The corner-sharing octahedra tilt angles range from 31–64°. There are a spread of Cd–O bond distances ranging from 2.29–2.51 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to four Cd2+ and one H1+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to two Cd2+ and one H1+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Cd2+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Cd2+ and one H1+ atom.
