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 Fm3¯m (No. 225) with a = 7.966(18) Å, V = 506(2) Å3 (In) and a = 7.9203(19) Å, V = 496.8(2) Å3 (Tl), Z = 4, while InAsF6 and TlAsF6 crystallize in a rhombohedral space group R3¯ (No. 148) with a = 7.5029(13) Å, c = 7.7462(19) Å, V = 377.64(13) Å3 (In) and a = 7.5084(9) Å, c = 7.6743(9) Å, V = 374.68(8) Å3 (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.
