Abstractdc.description.abstractThe new phases α-NaSbP2S6 and β-NaSbP2S6 were synthesized by ceramic and reactive flux methods at 773 K. The structures of α-NaSbP2S6 and β-NaSbP2S6 were determined by the single-crystal X-ray diffraction technique. α-NaSbP2S6 crystallizes in the monoclinic space group P21/c with a = 11.231(2) Å, b = 7.2807(15) Å, c = 11.640(2) Å, β = 108.99(3)°, V = 900.0(3) Å3 and z = 4. β-NaSbP2S6 crystallizes in the monoclinic space group P21 with a = 6.6167(13) Å, b = 7.3993(15) Å, c = 9.895(2) Å, β = 92.12(3) °, V = 484.10(17) Å3 and z = 2. The α- and β-phases of NaSbP2S6 are closely related, the main difference lies in the stacking of the [Sb[P2S6]]nn- layers. The structure of α-NaSbP2S6 consists of two condensed layers (MPS3 type) to give an ABAB... sequence with Na+ cations located in the interlayer space. The packing of β-NaSbP2S6 is formed by monolayers of [Sb[P2S6]]nn- stacked in an AA... fashion separated by a layer of Na+ cations. Both phases are derivates of the M1+M3+P2Q6 family. The op
