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-(dimethylamino)ethylamino]quinoline ligand and another chloride ion to form a distorted fac-CdN3Cl3 octahedron. The ethanol molecule 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.
