A trigonal dodecahedral cadmium(II) complex with zinc(II)-salen type metalloligand: Synthesis, structure, self-assembly and application in the detection of various nitroaromatics via turn-off fluorescence response

摘要： A compartmental Schiff base ligand, N,N'-bis(3-ethoxysalicylidene)-2,2-dimethylpropane-1,3-diamine (H2L) has been used to prepare a hetero-trimetallic cadmium(II)/zinc(II) complex, Cd{LZn(NCS)}2. Single crystal X-ray diffraction analysis has confirmed the structure of the complex. Cadmium(II) is octa-coordinated and it shows trigonal dodecahedral geometry. The complex behaves as a sensor for the detection of various nitroaromatics via turn-off fluorescence response.
