Materials Data on CsGaAs3H5O12 by Materials Project
Abstract
CsGaAs3H5O12 crystallizes in the monoclinic Cc space group. The structure is three-dimensional. Cs1+ is bonded to two H1+ and ten O2- atoms to form distorted CsH2O10 cuboctahedra that share corners with ten AsO4 tetrahedra and edges with two equivalent GaO6 octahedra. There are one shorter (3.34 Å) and one longer (3.37 Å) Cs–H bond lengths. There are a spread of Cs–O bond distances ranging from 3.16–3.52 Å. Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with six AsO4 tetrahedra and edges with two equivalent CsH2O10 cuboctahedra. There are a spread of Ga–O bond distances ranging from 1.99–2.05 Å. There are three inequivalent As5+ sites. In the first As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with four equivalent CsH2O10 cuboctahedra and corners with two equivalent GaO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There is two shorter (1.71 Å) and two longer (1.76 Å) As–O bond length. In the second As5+ site, As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with three equivalent CsH2O10 cuboctahedra and corners with two equivalent GaO6 octahedra. The corner-sharing octahedral tilt angles are 58°.more »
