| Popis: | The reaction of Cs2MoO4, K2MoO4, MoO3, Mo, and P2O5 in a mole ratio of 1:1:4.33:1.33:6 in an evacuated silica tube for 48 hr at 900°C yields dichroic crystals (green when viewed parallel to the normal of the {010} sets and yellow when viewed parallel to the normal of the {001} sets) of Cs2K2Mo8P12O52. The crystals are monoclinic, space group P2 1 c (#14) with a = 6.388(2), b = 18.901(2), c = 18.805(2)A, β = 92.07(2)°, and V = 2269.11(9)A3. The framework consists of (MoO6) octahedra, (PO4) phosphate, and (P2O7) pyrophosphate groups and contains two different types of parallel tunnel: a large tunnel in which an ordered array of Cs+ and voids are found and a smaller one filled with K+. |
