Crystal structure of bis{N-[2-(dimethylamino) ethyl] quinolin-8-amine kappa N-3,N',N''} nickel(II) dichloride 3.5-hydrate

In the title compound, [Ni(C13H17N3)(2)]Cl-2 center dot 3.5H(2)O,the geometry of the NiN6 complex cation is slightly distorted octahedral, with a facial arrangement of the two tridentate N-[2(dimethylamino) ethyl] quinolin-8-amine ligands around the metal ion. The asymmetric unit consists of two independent complex half-molecules located on centres of inversion, together with two chloride counter-anions and 3.5 water molecules of solvation, one of which is disordered across an inversion centre. In the crystal, O-H center dot center dot center dot O, O-H center dot center dot center dot Cl and N-H center dot center dot center dot Cl hydrogen-bonding interactions form a threedimensional network structure.
