Аннотация

The crystallographic analysis of the structures of [Hg7As4](AgI3)2 (I), [Hg6As4Br3](SnBr3) (II), and [Hg11As4](GaBr4)4 (III) treated as host-guest structures is performed. It is shown that the spatial basis (“skeleton”) of the structures is formed by crystallographic planes densely occupied by mercury and halogen atoms. The cubic symmetry of the first two structures is initiated by the local symmetry of the ([As2]Hg6) building block. The C2/m symmetry of the third structure is initiated by the 2/m local symmetry of the blocks with linear groups containing [Hg2] and [Hg3] fragments.
