Structural diversity in hybrid vanadium(IV) oxyfluorides based on a common building block
MetadataShow full item record
There are only limited reports on vanadium(IV) oxyfluorides (VOFs) with extended crystal structures. Here we expand and enrich the list of existing VOFs with a series of 14 new materials "VOF-n (n = 1-14)" prepared using ionothermal and solvothermal synthesis methods. All of these materials arise from the condensation of a dimeric structural motif. These VOFs can be classified into three groups depending on their key structural features; layer structures: VOF-1 "[HN2C7H6][V2O2F5]", VOF-2 "[HN2C4H4][V2O2F5]", VOF-3 "[HN2C3H4][V2O2F5]" and VOF-4 "V-2(N2C4H4)O2F4", ladder like structures: VOF-5 "[NH4(HN2C3H4)][V2O2F6]", VOF-6 "[K(HN2C3H4)][V2O2F6]", VOF-7 "[HNH2CH2CH3][VOF3]", VOF-8 "[HN2C7H6][VOF3]", VOF-9 "[H2N2C4H6][V2O2F6]", VOF-10 "beta-RbVOF3", VOF-11 "alpha-KVOF3", VOF-12 "beta-KVOF3", VOF-13 "[H-2(NH2)(2)(CH2)(2)][V2O2F6]", and a chain structure: VOF-14 "[H2N2C6H12][V2O2F7]". The crystal structures of VOF-n are presented, and their synthetic and structural relationships are discussed.
