  • Cs7Sm11[TeO3]12Cl16 and Rb7Nd11[TeO3]12Br16, the new tellurite halides of the tetragonal Rb6LiNd11[SeO3]12Cl16 structure type 

    Charkin, Dmitri O.; Black, Cameron; Downie, Lewis James; Sklovsky, Dmitry E.; Berdonosov, Peter S.; Olenev, Andrei V.; Zhou, Wuzong; Lightfoot, Philip; Dolgikh, Valery A. (2015-12) - Journal article
    Two new rare-earth – alkali – tellurium oxide halides were synthesized by a salt flux technique and characterized by single-crystal X-ray diffraction. The structures of the new compounds Cs7Sm11[TeO3]12Cl16 (I) and ...
  • Extending the family of V4+ S = ½ kagome antiferromagnets 

    Clark, Lucy Mary; Himeur, Farida Himeur; Black, Cameron; Athukorala Arachchige, Kasun Sankalpa; Slawin, Alexandra Martha Zoya; Morris, Russell Edward; Lightfoot, Philip (2015) - Journal article
    The ionothermal synthesis, structure, and magnetic susceptibility of a novel inorganic–organic hybrid material, imidazolium vanadium(III,IV) oxyfluoride [C3H5N2][V9O6F24(H2O)2] (ImVOF) are presented. The structure consists ...
  • Structural diversity in hybrid vanadium(IV) oxyfluorides based on a common building block 

    Aidoudi, Farida H.; Black, Cameron; Arachchige, Kasun S. Athukorala; Slawin, Alexandra M. Z.; Morris, Russell E.; Lightfoot, Philip (2014) - Journal article
    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 ...
  • Structural phase transitions in the kagome lattice based materials Cs2-xRbxSnCu3F12 (x = 0, 0.5, 1.0, 1.5)
