Light yellow single crystals of Na3TiCl6 and K3TiCl6 are obtained from the
binary components, TiCl3 and NaCl and KCl, respectively, in 1:3 molar ratio
s. Na3TiCl6 crystallizes with the cryolite type of structure (monoclinic, P
2(1)/n, Z = 2, a = 668,02(8), b = 709,13(6), c = 981,38(12) pm, beta = 90,3
1(2)degrees) while K3TiCl6 belongs to the K3MoCl6 type of structure (monocl
inic, P2(1)/c, Z = 1, a = 1262,6(2), b = 751,36(8), c = 1210,7(2) pm, beta
= 108,30(2)degrees).
