N2 - Salts of the type M+[FeV3]-·xH2O have been prepared (where M+ = alkali-metal cation, V- = violurate) and found to be diamagnetic. The crystal structure of the title compound [NH4][FeV3]·ca. 4.5H2O has been determined by X-ray diffraction and refined by least squares to R 0.07 for 3 868 observed reflections. Crystals are triclinic, space group P1, a = 16.242(3), b = 15.690(3), c = 9.848(2) Å, α = 90.95(2), β = 106.99(2), γ = 74.20(2)°, Z = 4. There are two independent cations and anions in the asymmetric unit; the geometry of the anion co-ordinated by three bidentate violurate ligands (V- = C4O4N3H2-) is fac (means: Fe-O 1.983, Fe-N 1.877 Å), and closely resembles that found in ferroverdin. The accuracy of the structure is inhibited by serious disorder among the solvent molecules in the lattice.
