Materials Data on SrCd2H16(Br3O4)2 by Materials Project
Sr(H2O)6(CdBr3)2(H2O)2 crystallizes in the orthorhombic P2_12_12 space group. The structure is one-dimensional and consists of four water molecules; two CdBr3 ribbons oriented in the (1, 0, 0) direction; and two Sr(H2O)6 ribbons oriented in the (1, 0, 0) direction. In each CdBr3 ribbon, Cd2+ is bonded to six Br1- atoms to form edge-sharing CdBr6 octahedra. There are a spread of Cd–Br bond distances ranging from 2.75–3.01 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a water-like geometry to two equivalent Cd2+ atoms. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Cd2+ atom. In the third Br1- site, Br1- is bonded in a 3-coordinate geometry to three equivalent Cd2+ atoms. In each Sr(H2O)6 ribbon, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.56–2.85 Å. There are six 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 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fifth 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 sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two equivalent H1+ atoms. In the second O2- site, O2- is bonded in a water-like geometry to one Sr2+ and two equivalent H1+ atoms. In the third O2- site, O2- is bonded in a water-like geometry to two equivalent Sr2+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a water-like geometry to one Sr2+ and two H1+ atoms.
