Title: Materials Data on Na2CdH4(SeO5)2 by Materials Project

Abstract

Na2CdH4(SeO5)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.42–2.75 Å. Cd2+ is bonded to six O2- atoms to form CdO6 octahedra that share corners with four equivalent SeO4 tetrahedra. There are four shorter (2.31 Å) and two longer (2.39 Å) Cd–O bond lengths. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.69 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.76 Å) H–O bond length. Se6+ is bonded to four O2- atoms to form SeO4 tetrahedra that share corners with two equivalent CdO6 octahedra. The corner-sharing octahedra tilt angles range from 47–55°. There are a spread of Se–O bond distances ranging from 1.66–1.69 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Na1+, one Cd2+, and two H1+more » atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one H1+, and one Se6+ atom. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Na1+, one Cd2+, and one Se6+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cd2+, and one Se6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one H1+, and one Se6+ atom.« less
