Two binuclear cadmium(II) iodide compounds of the types [Cd(L1)(I)] ( 1) and [(L2)Cd(µ-I)CdI] ( 2) [L1 = N, N′-(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 CdNI 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 chromophore surrounded by four iodides, while the other has a distorted trigonal bipyramidal environment with CdNI chromophore bound by four N atoms of L2 and one bridging iodide. Weak C-H···π 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 (π-π*) fluorescence in DMF solution at room temperature, whereas compound 2 containing tripodal amine is fluorescent-inactive.
