Abstract

Ca6Si3H2O13 crystallizes in the triclinic P-1 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 corners with five SiO4 tetrahedra.

There are a spread of Ca–O bond distances ranging from 2.33–2.56 Å. In the third Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to one H1+ and seven O2- atoms. The Ca–H bond length is 2.54 Å.

In the third O2- site, O2- is bonded to three Ca2+ and one Si4+ atom to form a mixture of distorted edge and corner-sharing OCa3Si trigonal pyramids. In the fourth O2- site, O2- is bonded to three Ca2+ and one Si4+ atom to form a mixture of distorted edge and corner-sharing OCa3Si trigonal pyramids. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Ca2+ and one Si4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to four Ca2+ and one H1+ atom. In the seventh O2- site, O2- is bonded to three Ca2+ and one Si4+ atom to form a mixture of distorted edge and corner-sharing OCa3Si trigonal pyramids. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ca2+ and two Si4+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to four Ca2+ and one H1+ atom. In the tenth O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one Si4+ atom. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to three Ca2+ and one Si4+ atom. In the twelfth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Ca2+ and one Si4+ atom. In the thirteenth O2- site, O2- is bonded in a 4-coordinate geometry to three Ca2+ and one Si4+ atom.« less
