Abstract

Ca5TiSn4(BO3)10 is Calcite-derived structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share a cornercorner with one TiO6 octahedra and corners with five SnO6 octahedra. The corner-sharing octahedra tilt angles range from 57–59°. There are a spread of Ca–O bond distances ranging from 2.39–2.47 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with six SnO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are five shorter (2.38 Å) and one longer (2.39 Å) Ca–O bond lengths. In the third Ca2+ site, Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with two equivalent SnO6 octahedra and corners with four equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 57°. There are two shorter (2.37 Å) and four longer (2.46 Å) Ca–O bond lengths. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six CaO6 octahedra. The corner-sharing octahedra tilt angles range from 57–59°. There is four shorter (1.99 Å) and two longer (2.00 Å) Ti–O bond length. There are five inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.39 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.39 Å. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.39 Å. In the fourth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.39 Å) B–O bond length. In the fifth B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. All B–O bond lengths are 1.39 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six CaO6 octahedra. The corner-sharing octahedra tilt angles range from 57–58°. There are one shorter (2.08 Å) and five longer (2.09 Å) Sn–O bond lengths. In the second Sn4+ site, Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six CaO6 octahedra. The corner-sharing octahedral tilt angles are 57°. All Sn–O bond lengths are 2.09 Å. There are fifteen inequivalent O2- sites.
