Question:
GeO2 exists in a number of structures, most commonly a hexagonal form that is built on corner sharing GeO4 tetrahedra and a tetragonal structure in the mineral argutite built from edge sharing GeO6 octahedra.
(a) Which of these two GeO2 structures will be favored if the sample is prepared under high pressure conditions. In framing your answer, you should comment on the likely difference of Ge-O bond distances in each structure.
(b) Giving your reasoning predict if a direct transformation between the hexagonal and tetragonal structures is likely to be first order or continuous.
