N2 - The synthesis and structural characterization of the complexes catena-[Cd(2,6-lutidine-N-oxide)(μ1,1-N3)(μ1,1,1-N3)] (1), catena-[Cd(μ2-2,6-lutidine-N-oxide)(μ1,3-NCS)2] (2), catena-[Zn(2,6-lutidine-N-oxide)(μ1,1-N3)2] (3) and [Zn(2,6-lutidine-N-oxide)2(NCS)2] (4) where 2,6-lutidine = 2,6-dimethylpyridine-N-oxide, are reported. Single crystal X-ray crystallography revealed the polymeric nature of complexes 1, 2, and 3 as a 1D double chains “ladder of defective cubane”, 2D with doubly μ(O,O) bridging of 2,6-lutidine-N-oxide and 1D, respective, and the monomeric nature of 4. The emission spectral properties of the complexes were investigated and fluorescence enhancement was observed for complexes 2–4.
