K 2 W 6 Br 14 (I), Rb 2 W 6 Br 14 (II), and Cs 2 W 6 Br 14 (III) were formed by reactions of W 6 Br 12 with the corresponding alkali metal bromides in evacuated silica tubes with a temperature gradient of 925 K/915 K. (I) crystallizes in the cubic space group Pn3 (no. 201), a = 13.808 A Γ , Z = 4, c
