title: Dichlorido{N,N-dimethyl-N'-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine-κN,N',N''}zinc.
abstract: The asymmetric unit of the title compound, [ZnCl(2)(C(11)H(17)N(3))], contains two independent penta-coordinate Zn(II) complex mol-ecules. In each mol-ecule, the metal atom is coordinated by an N,N',N''-tridenate Schiff base and two Cl atoms in a distorted square-pyramidal geometry. The two mol-ecules differ little in their geometry, but more in their inter-molecular inter-actions. In the crystal, adjacent mol-ecules are connected via C-H⋯Cl inter-actions into a three-dimensional supra-molecular structure. The network is supplemented by π-π inter-actions formed between the aromatic rings of pairs of the symmetry-related mol-ecules [centroid-centroid distances = 3.6255 (10) and 3.7073 (10) Å]. The crystal lattice contains void spaces with a size of 52 Å(3).
