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

In the title compound, [Ni(C(13)H(17)N(3))(2)]Cl(2)·3.5H(2)O, the geom­etry of the NiN(6) 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⋯O, O—H⋯Cl and N—H⋯Cl hydrogen-bonding inter­actions form a three-dimensional network structure.
