Six Mo dimers arranged around a central PO4 tetrahedron form the core of the novel ε-Keggin polyoxocation [ε-PMo12O36(OH)4{La(H2O)4}4]5+ (see structure) capped with four {La(H2O)4}3+ units. A 31P NMR spectroscopy study shows that the ε-Keggin ion is unstable in aqueous solution, and leads to the formation of a polyanion/polycation salt, which is crystallographically characterized.

Crystal data and structure refinements for 1: a dark red cubic crystal (0.18×0.18×0.16 mm) was analyzed with a Siemens SMART three-circle diffractometer equipped with a CCD bidimensional detector using MoKα monochromatized radiation (λ=0.71073 Å). Cubic, space group P
3m, a=12.2256(1) Å, V=1827.30(3) Å3, Z=1, ρcalcd=2.757 g cm−3, μ(MoKα)=7.105 mm−1, F(000)=1370, 13 173 reflections measured, of which 1030 were independent, 57 refined parameters, R=0.0572, wR2=0.1474. 2: a dark red crystal (0.34×0.22×0.22 mm); cubic, space group P
3m, a=12.4193(1) Å, V=1915.54(3) Å3, Z=1, ρcalcd=2.437 g cm−3, μ(MoKα)=4.344 mm−1, F(000)=1280, 8636 reflections measured, of which 990 were independent, 69 refined parameters, R=0.0701, wR2=0.1766. 3: a dark brown plate (0.14×0.12×0.04 mm); tetragonal, space group P
, a=20.2354(2), c=12.3785(2) Å, V=5068.6(1) Å3, Z=2, ρcalcd=3.182 g cm−3, μ(MoKα)=4.857 mm−1, F(000)=4460, 23 474 reflections measured, of which 7289 were independent, 399 refined parameters, R=0.0657, wR2=0.1248. All the molybdenum and phosphorus atoms of the Keggin ions were refined anisotropically while the potassium, oxygen, and chlorine atoms were refined by using isotropic temperature factors. For 1, 2, and 3, data reduction was performed with the SAINT software. The absorption correction was based on multiple and symmetry-equivalent reflections in the data set using the SADABS program based on the method of Blessing. The structures were solved by direct methods and refined by full-matrix least-squares using the SHELX-TL package.
