Abstract

The crystal structure of Cs3Mo6P10O38 has been determined from single-crystal X-ray diffraction data. It crystallizes in the triclinic space group P1 with a = 9.511(3), b = 14.232(4), c = 6.437(5), Å, α = 91.15(5), β = 105.92(5), γ = 90.04(2)°, V = 838(1), Å3, Z = 1, R = 0.057, Rw = 0.066, GOF = 1.97 for 1460 reflections with I > 2.5 σ(I). The structure contains several different types of tunnels of which two are occupied by Cs+. The structural formula is Cs3(Mo)2(Mo2O)2(PO4)2(P2O7)4. It is a mixed-valence molybdenum phosphate in which Mo3+ and Mo4+ are simultaneously present. The structural relationship between the title compound and Cs4Mo8P12O52 is discussed.
