Cadmium(II) iodide when reacted separately with β-picoline-N-oxide(L) and ϒ-picoline-N-oxide(L') in ethanolic medium formed two crystalline compounds having the composition CdLI₂ and CdL'I₂. These are apparently three coordinated but are presumably tetrahedral through dimerisation. These dimers were separately reacted with nitrogen donor ligands like quinoline and isoquinoline(L") in a mixed solvent medium and mixed ligand complexes were characterised by analysis and i.r. spectra.
