ZnBr2 crystallizes in the same structure as ZnI2: four tetrahedral Zn centers share three vertices to form “super-tetrahedra” of nominal composition {Zn4Br10}2−, which are linked by their vertices to form a three-dimensional structure.
The crystal structure of zinc bromide is analogous to that of zinc iodide: four tetrahedral zinc atoms share three vertices to form "super-tetrahedra" with a nominal composition of {Zn4Br10}2−. These super-tetrahedra are linked by their vertices, forming a three-dimensional network.
