Silver(I) tetrafluoridooxidovanadate(V) - Ag[VOF4]
Abstract:
Silver(I) tetrafluoridooxidovanadate(V) which contains the polymeric chain anion, [VOF(4)](nn-), has been prepared in reaction between AgNO(3) and VOF(3) in anhydrous HF solvent and characterised in the solid state by single-crystal X-ray diffraction and Raman spectroscopy. Pale yellow crystals of Ag[VOF(4)] crystallise in a monoclinic P2(1)/c space group with a = 5.5452(4) Å, b = 5.0071(3) Å, c = 13.6511(11) Å, beta = 100.543(3)°, and V = 372.63(5) Å(3) at 200 K with Z = 4. The most intense feature in the Raman spectrum is the V=O stretching band of the anion at 1008 cm-1. Solid-state conformational isomerism exists between [VOF(4)](-) anions in crystal structures of Ag[VOF(4)] and previously reported and structurally characterised K[VOF(4)] and Cs[VOF(4)] salts.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
