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 (10 n ) 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.
