Bis(μ-4-amino-3,5-dimethyl-4H-1,2,4-triazole-κ2N1:N2)bis(dibromidozinc)
Abstract
The centrosymmetric dimeric title complex, [Zn2Br4(C4H8N4)2], is isotypic with its [Zn2Cl4(C4H8N4)2], [Zn2I4(C4H8N4)2] and [Co2Cl4(C4H8N4)2] analogues. The zinc atom is bonded to two N atoms belonging to triazole bridging rings and to two terminal bromide ligands, in a geometry close to tetrahedral. Weak N—H...Br hydrogen bonds, with the amine functions as donor groups, are observed in the crystal structure, forming a three-dimensional supramolecular network.
