چکیده
In the title compound, [ZnI(2)(C(24)H(16)N(6))], the Zn(II) ion is five-coordinated in a distorted trigonal-bipyramidal geometry by an N,N,N-tridentate 2,3,5,6-tetra-2-pyridinylpyrazine ligand and two iodide ions. The I(-) ions both occupy equatorial sites. Within the ligand, the dihedral angles between the central pyrazine ring and the two chelating pyridine (py) rings are 14.74 (17) and 26.72 (18)°. The equivalent angles for the non-coordinating py rings are 28.63 (16) and 42.19 (17)°. There is no aromatic π-π stacking in the crystal.
