Abstract
This paper describes the arrangement of cations in the structures of inorganic compounds HgVO3, HgReO4, Hg2MoO4 (α and β, Hg2Mo2O7, Hg2Mo5O16, Hg5Re2O10 (two modifications), Hg2ReO5, and Hg2VO4. To isolate crystal-forming planes and cation sublattices, it is preferable to consider the [Hg2]2+ dumbbell pair as a single cation. Two types of mutual orientation of close-packed cation planes intersecting at an angle of ∼60° or ∼90° (45°) have been found. Details of three-dimensional ordering of cations and possible methods of structure modification in polymorphous transformations are discussed.
