A needle crystal with a hexagonal section was selected; reflections and 122 variables. The structure of NaTi 2 (PS 4 ) 3 is due to its air instability, it was necessary to put it in a built up from TiS 6 octahedra and PS 4 tetrahedra linked to each sealed-off Lindemann glass capillary. The Laue pattern other only by edges. One TiS 6 group is bonded to three PS 4 showed a hexagonal symmetry and systematic absences units and one PS 4 unit to two TiS 6 groups. It exhibits very wide (0kl, h0l, and hhl: l Ο 2n) on precession and Weissenberg tunnels along the c axis.
