Materials Data on Na2Si(H5O4)2 by Materials Project
Abstract
Na2Si(H5O4)2 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Na2Si(H5O4)2 sheet oriented in the (0, 0, 1) direction. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Na–O bond distances ranging from 2.32–2.56 Å. In the second Na1+ site, Na1+ is bonded to five O2- atoms to form NaO5 trigonal bipyramids that share a cornercorner with one SiO4 tetrahedra. There are a spread of Na–O bond distances ranging from 2.33–2.39 Å. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one NaO5 trigonal bipyramid. There are a spread of Si–O bond distances ranging from 1.63–1.69 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.67 Å) H–O bond length. In the second 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 third H1+ site, H1+ is bonded in a single-bond geometrymore »
