Di-chlorido-{8-[2-(di-methyl-amino)-ethyl-amino]-quinoline-κ(3) N,N',N''}zinc

Di-μ-chlorido-bis-(chlorido-{8-[2-(di-methyl-amino)-ethyl-amino]-quinoline}-cadmium) ethanol monosolvate

The title solvated bimetallic complex, [Cd2Cl4(C13H17N3)2]·C2H5OH, comprises two Cd2+ metal ions linked by a pair of μ2 Cl- ions. The coordination sphere around each Cd2+ ion is completed by three N atoms of a tridentate 8-[2-(di-methyl-amino)-ethyl-amino]quinoline ligand and another chloride ion to form a distorted fac-CdN3Cl3 octa-hedron. The ethanol mol-ecule is both an acceptor of an N-H⋯O and a donor of an O-H⋯Cl hydrogen bonds to its adjacent complex unit. In the crystal, weak aromatic π-π stacking is observed.

Crystal structure of bis-{N-[2-(di-methyl-amino)-eth-yl]quinolin-8-amine-κ(3) N,N',N''}nickel(II) dichloride 3.5-hydrate

In the title compound, [Ni(C13H17N3)2]Cl2·3.5H2O, the geom-etry of the NiN6 complex cation is slightly distorted octa-hedral, with a facial arrangement of the two tridentate N-[2-(di--methyl-amino)-eth-yl]quinolin-8-amine ligands around the metal ion. The asymmetric unit consists of two independent complex half-mol-ecules located on centres of inversion, together with two chloride counter-anions and 3.5 water mol-ecules 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 inter-actions form a three-dimensional network structure.
