Abstract

Na4Be2SnSi6(HO5)4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.42–2.77 Å. In the second Na1+ site, Na1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.43–2.86 Å. There are two inequivalent Be2+ sites. In the first Be2+ site, Be2+ is bonded to four O2- atoms to form BeO4 tetrahedra that share corners with four SiO4 tetrahedra and an edgeedge with one BeO4 tetrahedra. There is two shorter (1.59 Å) and two longer (1.68 Å) Be–O bond length. In the second Be2+ site, Be2+ is bonded to four O2- atoms to form BeO4 tetrahedra that share corners with four SiO4 tetrahedra and an edgeedge with one BeO4 tetrahedra. There is two shorter (1.59 Å) and two longer (1.69 Å) Be–O bond length. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six SiO4 tetrahedra. There are a spread of Sn–O bond distances ranging from 2.06–2.09 Å. There aremore » three inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SnO6 octahedra, a cornercorner with one BeO4 tetrahedra, and corners with two SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There are a spread of Si–O bond distances ranging from 1.61–1.66 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SnO6 octahedra, a cornercorner with one BeO4 tetrahedra, and corners with two SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 49°. There are a spread of Si–O bond distances ranging from 1.61–1.66 Å. In the third Si4+ site, Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share a cornercorner with one SnO6 octahedra, corners with two BeO4 tetrahedra, and corners with two SiO4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. There is one shorter (1.62 Å) and three longer (1.64 Å) Si–O bond length. There are two 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 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted T-shaped geometry to two Be2+ and one Si4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Na1+, one Be2+, and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Na1+ and two Si4+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Sn4+, and one Si4+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Na1+ and two Si4+ atoms. In the sixth O2- site, O2- is bonded to two equivalent Na1+, one Sn4+, and one Si4+ atom to form distorted corner-sharing ONa2SiSn tetrahedra. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to two Na1+ and two H1+ atoms. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Na1+, one Be2+, and one Si4+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Na1+ and two Si4+ atoms. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Sn4+, and one Si4+ atom.« less
