title: catena-poly[[(acetonitrile-N)dichlorocopper(II)]-mu-2,5-dimethylpyrazine-kappa2N:N'].
abstract: In the structure of the title compound, [CuCl2(C2H3N)(C6H8N2)], each Cu2+ cation is surrounded by two 2,5-dimethylpyrazine ligands, one acetonitrile ligand and two Cl- anions within a distorted tetragonal pyramid. The acetonitrile ligand, which forms the apex of the pyramid, the Cu2+ cation and the Cl- anions are all located in general positions, whereas each of the 2,5-dimethylpyrazine ligands is located about a centre of inversion. The 2,5-dimethylpyrazine ligands connect the Cu2+ cations via mu-N:N' coordination to form chains.
