description: Nb3Te4O15Cl crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are three inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedral tilt angles are 23°. There are a spread of Nb–O bond distances ranging from 1.85–2.24 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 6–29°. There are a spread of Nb–O bond distances ranging from 1.89–2.17 Å. In the third Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted corner-sharing NbO6 octahedra. The corner-sharing octahedra tilt angles range from 6–29°. There are a spread of Nb–O bond distances ranging from 1.82–2.28 Å. There are four inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.89–1.93 Å. The Te–Cl bond length is 3.23 Å. In the second Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. All Te–O bond lengths are 1.91 Å. The Te–Cl bond length is 3.30 Å. In the third Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.89–1.93 Å. The Te–Cl bond length is 3.34 Å. In the fourth Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- and one Cl1- atom. There are a spread of Te–O bond distances ranging from 1.89–1.92 Å. The Te–Cl bond length is 3.22 Å.
