(6,6'-Dimethyl-2,2'-bipyridine-?N,N')diiodidozinc(II).

ABSTRACT: The complete mol-ecule of the title compound, [ZnI(2)(C(12)H(12)N(2))], is generated by crystallograpic twofold symmetry, with the Zn(II) atom lying on the rotation axis. The Zn(II) atom is coordinated by the N,N-bidentate 6,6'-dimethyl-2,2'-bipyridine ligand and two iodide ions, resulting in a distorted ZnN(2)I(2) tetra-hedral geometry for the metal. In the crystal, there are weak ?-? contacts between the pyridine rings [centroid-centroid distance = 3.978?(3)?Å].
