In the title complex, [ZnCl2(C13H17N3)], the coordination sphere of the zinc cation is distorted square pyramidal. The three N atoms of the N,N',N''-tridentate 8-[2-(dimethylamino)ethylamino]quinoline ligand and one chloride ion constitute a considerably distorted square base. The apical site is occupied by another chloride ion. The distortion from the ideal square-pyramidal geometry is manifested by the N-Zn-N angle of 133.25 (11)°. Like most square-pyramidal metal complexes, the zinc cation is displaced towards the apical chloride ion. In the crystal, molecules are linked by N-HCl interactions. This leads to the formation of chains of molecules parallel to the b-axis direction.

I would like to thank Professor P. G. Edwards of Cardiff University, School of Chemistry, for providing me with many opportunities to work in his laboratory as an academic visitor as well as for his invaluable advice and financial support, without which this work as well as others would not have been possible. Furthermore, I would like to thank Dr Benson M. Kariuki for the X-ray structure determination of the title complex.
