Metal complexes of the alkaloid 4-formyl-8-hydroxy-quinoline occurring in the timber of Broussonetia zeylanica (THW.) corner

Several complexes of the li and 4-formy'l-8-hydrox quinoline with the metal ions. Ni⁺, Zn², CU²⁺, Cd²⁺, Mn²⁺, Mg², Al³⁺, Fe³⁺ and MoO₂²⁺ have been synthesized. Their compositions have been charactcrised from elemental analyses and spectroscopic data. These studies may bear some relevance to the role of naturally occurring ligands in the metal ion translocation in plants.
