چکیده
There are two independent mol-ecules in the asymmetric unit of the title compound, C(11)H(9)Cl(2)N, both of which are essentially planar [maximum deviations of 0.072 (5) and 0.072 (7) Å]. In the crystal structure, weak π-π stacking inter-actions [centroid-centroid distances = 3.791 (3) Å and 3.855 (3) Å] link pairs of mol-ecules.

The crystal of the title compound, [Zn(C(7)H(3)Cl(2)O(2))(2)(H(2)O)(2)](2)·[Zn(2)(C(7)H(3)Cl(2)O(2))(4)(H(2)O)(2)], consists of monomeric and dimeric Zn(II) complexes. Both complexes afford a six-coordinated coordination environment about the Zn atoms with cis-configuration ligands. The deprotonated hydr-oxy groups of the 3,5-dichloro-salicylaldehyde ligands bridge two metal cations, forming a ...
