Three Distinct Silver(I) Coordination Polymers: Bridging‐Ligand Directed Syntheses, Crystal Structures, Luminescence, and Nitrobenzene Sensing Properties

Three distinct Ag I ‐DMAP [DMAP = 4‐(dimethylamino)pyridine] coordination polymers [Ag 2 I 2 (DMAP) 2 ] n ( 1 ), [Ag 2 (CN) 2 (DMAP) 2.5 · DMAP] n ( 2 ), and [Ag(SCN)(DMAP)] n ( 3 ) were constructed by monatomic I – , diatomic CN – , and triatomic SCN – bridges, respectively. 1 – 3 were determined by FT‐IR spectroscopy, elemental analyses, TGA, powder and single‐crystal X‐ray diffraction. 1 exhibits a 1D wavelike chain structure, sustained by 3‐connected I – bridges, whereas 2 shows a unique 1D single‐ and double‐strand alternating chain, supported by 3‐connected CN – bridges. Compound 3 has a 2D 3‐connected network architecture, fabricated by 3‐connected SCN – bridges, and exhibits a (4 · 8 2 ) topology. The luminescence and nitrobenzene sensing properties of 1 – 3 were explored in 2‐propanol suspensions, which revealed that compounds 1 – 3 exhibit DMAP originated luminescence emissions and are highly sensitive for nitrobenzene detection.
