Abstract
AbstractTwo Ag(I) coordination polymers (CPs), namely [Ag(bpetan)(NO3)]n (CP1) and {[Ag(bpetan)]2(iph).8H2O}n (CP2) [where bpetan=1,2‐bis(4‐pyridyl)ethane, H2iph= isophthalic acid] were synthesized and characterized using elemental analysis, IR, UV‐Vis, fluorescence spectroscopy, and single crystal X‐ray diffraction. Both the CPs crystallize in triclinic system and the crystal structures comprise [Ag(bpetan)]nn+ polymers that are linked by nitrate ions to give rise to a corrugated 2D infinite rectangular net in CP1. On the other hand, isophthalate ions in 2 do not participate in coordination and together with lattice water molecules are encapsulated between the [Ag(bpetan)]nn+ chains. A structural comparison of CP1 and CP2 was done with compounds of same stoichiometry but crystallizing in different space groups. The band gap energies of CP1 and CP2 were calculated to assess their photocatalytic activity, and the latter was found to act as a more efficient photocatalyst to degrade the methylene blue dye. In addition CP2 offers a better anti‐bacterial, cytotoxicity and hemolytic activity than CP1.
