Abstract
Five silver coordination polymers, namely, {[Ag(3,3′-daps)2]·BF4}n (1), {[Ag(3,3′-daps)2]·NO3}n (2), [Ag(3,3′-daps)(CF3SO3)]n (3), {[Ag(4,4′-daps)]·CF3SO3}n (4), and {[Ag(4,4′-daps)]·ClO4}n (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 single-crystal 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 44-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.
