Anion-controlled assembly of silver-di(aminophenyl)sulfone coordination polymers: Syntheses, crystal structures, and solid state luminescence

Five silver coordination polymers, namely, {[Ag(3,3 '-daps)(2)] center dot BF4}(n) (1), {[Ag(3,3 '-daps)(2)] center dot NO3}(n) (2), [Ag(3,3 '-daps)(CF3SO3)](n) (3), {[Ag(4,4 '-daps)] center dot CF3SO3} (4), and {[Ag(4,4 '-daps)] center dot Claan (5) (3,3 '-daps= di (3 '-aminodiphenyl)sulfone, and 4,4 '-daps=di(4 '-aminodiphenyl)sulfone) have been synthesized and structural characterized by elemental analyses, IR spectra, powder X-ray diffraction (PXRD) and singlecrystal X-ray diffraction analyses. Complex 1 displays a 1D ladder-like chain with four-connected Ag ions and bridged 3,3 '-daps. Complex 2 shows other 1D ladder chain modified by tentacles. Complex 3 is a 2D layer structure with both Ag ions and 3,3 '-daps are 3-connected nodes. Complex 4 is another 1D ladder chain with three-connected Ag ions and 4,4 '-daps. Complex 5 shows a 2D 4(4)-sql net with Ag ions and 4,4 '-daps as 4-connected nodes. Moreover, their solid state luminescence and thermal stabilities also have been investigated.
