摘要：

The title structure, [ZnBr2(C2H8N2)], is made up of infinite -ZnBr2n(en)-ZnBr2-(en)- zigzag chains. Each repeat unit contains a trans ethylenediamine ligand [N-C-C-N -179 (1)degrees], which bridges two approximately tetrahedral but crystallographically distinct Zn atoms. One Zn atom is bisected by a crystallographic twofold axis, whereas the other has mirror symmetry. Even though the crystal packing does not allow significant interaction between Zn and N atoms on adjacent chains, it does facilitate extensive intermolecular N- H . . . Br hydrogen bonding (N . . . H 2.69-2.96 Angstrom).
