Ligand- and Anion-Directed Assembly of Exo-Coordinated Mercury(II) Halide Complexes with O₂S₂-Donor Macrocycles

Assembly reactions of mercury(II) halides (Cl, Br, and I) with two O2S2 macrocycles (L1 and L2) having different interdonor (S···S) distances were investigated, and four types of supramolecular complexes (1−4b) were obtained depending on the S···S distances as well as the size of the halide anions. Photoluminescence of these compounds was also studied.
