Abstract:
The title compound, [Ta(6)Br(12)(H(2)O)(6)](Br(0.4)Cl(1.6)) x 8H(2)O, crystallizes in space group P 1 macro. The structure contains two crystallographically independent [Ta(6)Br(12)(H(2)O)(6)](2+) cluster cations forming distinct layers parallel to the ab plane. The compound is isoconfigurational with the double salts [Ta(6)Br(12)(H(2)O)(6)]X(2) x trans-[Ta(6)Br(12)(OH)(4)(H(2)O)(2)] x 18H(2)O (X = Cl, Br).
