Single crystal structures of InPF6, InAsF6, TlPF6 and TlAsF6

The crystal structures of InPF6, TlPF6, InAsF6 and TlAsF6 have been determined from single-crystal X-ray diffraction data collected at 200 K. InPF6 and TlPF6 crystallize in the cubic space group F m 3 ¯ m (No. 225) with a = 7.966(18) A, V = 506(2) A3 (In) and a = 7.9203(19) A, V = 496.8(2) A3 (Tl), Z = 4, while InAsF6 and TlAsF6 crystallize in a rhombohedral space group R 3 ¯ (No. 148) with a = 7.5029(13) A, c = 7.7462(19) A, V = 377.64(13) A3 (In) and a = 7.5084(9) A, c = 7.6743(9) A, V = 374.68(8) A3 (Tl), Z = 3. In [AsF6]− salts, In+ and Tl+ cations are coordinated by 12 F atoms. In the crystal structures of InPF6 and TlPF6 disordered [PF6]− anions are present.
