Popis: X-band EPR spectra have been recorded at room temperature for VO2+ impurity in single crystals of tris-Guanadiniumhexafluoroaluminate, [C(NH2)3]3 AIF6. 19F super hyperfine structure has been observed on the 51V hyperfine lines. VO2+ replaces Al3+ to form an effective VOF5 complex. There are three possible V-O bond orientations in the AIF6 octahedron but with differing occupancy factors. Bonding parameters have been evaluated.
