Structure
Crystalline ZnBr2 adopts 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 dihydrate ZnBr2 · 2H2O also has a usual structure and should be described as Zn(H2O)6 Zn2Br6, where the Zn2Br62− ion has bromine bridges linking the two zinc atoms. A similar structure is found in the dimeric form of aluminium bromide (Al2Br6).
Gaseous ZnBr2 is linear in accordance with VSEPR theory with a Zn-Br bond length of 221 pm.

Famous quotes containing the word structure:
“A special feature of the structure of our book is the monstrous but perfectly organic part that eavesdropping plays in it.”
—Vladimir Nabokov (18991977)
“Vashtar: So its finished. A structure to house one man and the greatest treasure of all time.
Senta: And a structure that will last for all time.
Vashtar: Only history will tell that.
Senta: Sire, will he not be remembered?
Vashtar: Yes, hell be remembered. The pyramidll keep his memory alive. In that he built better than he knew.”
—William Faulkner (18971962)
“Just as a new scientific discovery manifests something that was already latent in the order of nature, and at the same time is logically related to the total structure of the existing science, so the new poem manifests something that was already latent in the order of words.”
—Northrop Frye (b. 1912)
