Title: Materials Data on Ca4Si3H2O11 by Materials Project

Abstract

Ca4Si3H2O11 crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. there are six inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share a cornercorner with one CaO6 octahedra, corners with five SiO4 tetrahedra, and edges with two CaO6 octahedra. The corner-sharing octahedral tilt angles are 46°. There are a spread of Ca–O bond distances ranging from 2.34–2.44 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share a cornercorner with one CaO6 octahedra, corners with five SiO4 tetrahedra, and edges with two CaO6 octahedra. The corner-sharing octahedral tilt angles are 29°. There are a spread of Ca–O bond distances ranging from 2.28–2.43 Å. In the third Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.84 Å.

The H–O bond length is 0.98 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ca2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Ca2+ and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Ca2+ and two Si4+ atoms.

In the seventh O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ca2+ and one Si4+ atom. In the eighth O2- site, O2- is bonded to three Ca2+ and one Si4+ atom to form distorted edge-sharing OCa3Si trigonal pyramids. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to two Ca2+, one Si4+, and one H1+ atom. In the tenth O2- site, O2- is bonded in a 2-coordinate geometry to two Ca2+, one Si4+, and one H1+ atom. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to three Ca2+ and one H1+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to four Ca2+ and one H1+ atom.« less
