In the title compound, [ZnBr(2)(C(24)H(16)N(6))], the Zn(II) ion is coordinated by the N,N',N''-tridentate 2,3,5,6-tetra-2-pyridyl-pyrazine ligand and two bromide ions, generating a distorted ZnN(3)Br(2) trigonal-bipyramidal geometry for the metal ion, with both bromide ions in equatorial sites. The dihedral angles between the pyrazine ring and the coordinated pyridine rings are 13.3 (2) and 24.8 (2)°; those between the pyrazine ring and the uncoordinated pyradine rings are 31.3 (2) and 44.2 (2)°. In the crystal, inversion dimers linked by pairs of weak C-H⋯Br hydrogen bonds occur.
