Two binuclear cadmium(II) iodide compounds of the types [Cd 2 (L1)(I) 4 ] (1) and [(L2)Cd(l-I)CdI 3 ] (2) [L1 = N,N 0 -(bis(pyridine-2-yl)formylidene)triethylenetetramine and L2 = tris(2-aminoethyl)amine] are synthesized and characterized. X-ray structural study shows that each cadmium(II) in 1 has a distorted square pyramidal geometry with a CdN 3 I 2 chromophore and that L1 behaves as a binucleating bis(tridentate) ligand bridging the metal centers with iodides remaining as terminals. In 2, one cadmium(II) adopts a distorted tetrahedral geometry with a CdI 4 chromophore surrounded by four iodides, while the other has a distorted trigonal bipyramidal environment with CdN 4 I chromophore bound by four N atoms of L2 and one bridging iodide. Weak C-HÁÁÁp interactions in 1 result in an infinite 1D chain; however, such weak non-covalent interactions are absent in 2. The Schiff base complex, 1, shows high-energy intraligand 1 (p-p*) fluorescence in DMF solution at room temperature, whereas compound 2 containing tripodal amine is fluorescent-inactive.Keywords Cadmium(II) iodide Á Schiff base bridge Á Tripodal amine Á X-ray structure Á Luminescence
