The crystal structures of Co₃(AsO₄)₂, Co₂₄ٜ₂As₉O₄₈, Co₂As₂O₇ and Co₇As₃ٜ₆O₁₆ have been determined by x-ray diffraction methods. The crystal structure of Mg₃(VO₄)₂ have been refined using single crystal x-ray diffraction data. General structural relations between M₃(XO₄)₂ type compounds where M refers to a divalent cation with radius comparable to that of cobalt, and x = As or V, are discussed. The deviations from ideality in cation polyhedral groups in crystal structures are analysed. / Thesis / Doctor of Philosophy (PhD)
