The title compound, C(15)H(15)NO(2), adopts the enol-imine tautomeric form. The dihedral angle between the two benzene rings is 48.1 (1)°. Intra-molecular O-H⋯N and O-H⋯O hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal, mol-ecules are linked into centrosymmetric R(2) (2)(10) dimers via pairs of O-H⋯O hydrogen bonds and the dimers may interact through very weak by...

The binuclear title complex, [Cu(2)Cl(4)(C(14)H(14)N(2))(2)], is located on a crystallographic inversion centre. The Cu(II) ion is in a distorted square-pyramid coordination environment formed by the bichelating N-heterocyclic ligand, two bridging Cl atoms and one terminal Cl atom. One of the bridging Cu-Cl bonds is significantly longer than the other.
