Abstract: A novel supramolecular compound of europium(III), {[Eu(CH3OH)6(H2O)2][PMo12O40]}·(C14H20O5)2·(CH3OH)2·(CH3CN)2 (1) (where C14H20O5 is benzo-15-crown-5), was synthesised and structurally characterized by single-crystal X-ray diffraction, FT-IR, FT-Raman, 1H and 13C NMR, 31P MAS NMR and elemental analysis. Compound 1 crystallizes in the triclinic space group, with a=13.821(3), b=15.417(3), c=20.786(4) Å, α=96.10(3), β=99.79(3) and γ=91.17(3)°, V=4336.6(15) Å3, Z=2 and R1(wR2)=0.0894(0.2346).
