Despite several types of fluorescent sensing molecules have been proposed and examined to signal Hg2+ ion binding, the development of fluorescence‐based devices for in‐field Hg2+ detection and screening in environmental and industrial samples is still a challenging task. Herein, we report the synthesis and characterization of three new coumarin‐based fluorescentchemosensors featuring mixed thia/aza

heterobinuclear (Ag+/Pd2+) complexes (1−6) of an NS2-donor macrocycle L with discrete and networked forms were prepared and structurally characterized. Reaction of L with HgCl2 afforded a unique 1:1 (cationic/anionic) complex [Hg2(L)Cl5][Hg(L)Cl] (1). Reaction of L with Hg(ClO4)2 yielded the sandwich-type 1:2 (metal-to-ligand) complex [Hg(L)2](ClO4)2 (2). Contrasting with the mercury(II) salts, the reactions

types and coordination modes including mono- to multinuclear and discrete to continuous ones, are shown to occur. Reactions of these ligand isomers with AgI salts (ClO4− and NO3−) afforded four complexes (1–4): the monomer (1 : 1, metal-to-ligand) complex with a trigonal bipyramid (TBP) geometry [Ag(o-L)ClO4] (1), the anion-free cyclic dimer (2 : 2) complex with two separated units, [Ag2(m-L)2]2(ClO4)4
