Abstract

Na~6~[Ti~5~O~12~(OH)~2~] is the first structurally characterized sodium oxohydroxotitanate. The compound can be prepared via hydrothermal treatment of TiO~2~ (Anatas) in NaOH (10n) for 96 h at 250° in an autoclave. The crystal structure of Na~6~[Ti~5~O~12~(OH)~2~] consists of infinite ribbons $\rm{{_{\infty }^{1}}}$[Ti~5~O~12~(OH)~2~]^6−^. The orthorhombic arrangement has Pbcn (No. 60) symmetry with the lattice constants a=18.668(4) Å, b=6.5333(13) Å, and c=9.829(2) Å.
