Unit cell dimensions of seven oxofluorometallates of transition metals were investigated by powder X-ray diffraction method. The compounds K3NbO2F4 and K3TaO2F4 were found to be isomorphous with cubic (FCC) structure and having lattice parameters 8.885 and 8.942 Å respectively. Similarly, the compounds K2NbOF5 (a = 8.367 Å, c = 13.038 Å) and K2TaOF5 (a = 8.463 Å, c = 13.139 Å) were also found to be isomorphous with a tetragonal structure. The compound K3Zr2O2F7 (a = 9.367 Å) was found to possess a cubic (FCC) structure. Both K2V2O5F2 (a = 6.739 Å, c = 10.635 Å) and K2VO3F (a = 5.984 Å, c = 10.914 Å) have a hexagonal structure.
