The crystal structure of AgMo5P8O33 has been determined from single-crystal X-ray diffraction data. AgMo5P8O33 crystallizes in the monoclinic space group I2 a (#15) with a = 23.050(8), b = 4.831(4), c = 22.935(9), Å, β = 90.42(5)°, V = 2554(4), Å3, Z = 4, R = 0.086 (Rw = 0.089) for 879 reflections with F2o > 3.0σ(F2o). The structure consists of large tunnels where the silver atoms are located. The framework is built up from MoO6 octahedra and P2O7 groups. The connectivity formula for AgMo5P8O33 is Ag(MoO 1 1O 4 2)(MoO 1 1O 5 2)4(P2O 1 1O 6 2)4. Powder magnetic susceptibility data confirm the presence of Mo5+ (d1) ions with spin 1 2, and a featureless antiferromagnetic ordering appears to occur below 2.5 K. Magnetization isotherms at 1.3 and 4.2 K in magnetic fields up to 65 kG are reported. The lithium, sodium, calcium, strontium, barium, and lead analogs of AgMo5P8O33 were also prepared.
