Two Ag(I) coordination polymers (CPs), namely [Ag(bpetan)(NO 3 )] n (CP 1 ) and {[Ag(bpetan)] 2 (iph).8H 2 O} n (CP 2 ) [where bpetan=1,2‐bis(4‐pyridyl)ethane, H 2 iph= 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)] n n + polymers that are linked by nitrate ions to give rise to a corrugated 2D infinite rectangular net in CP 1 . 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)] n n + chains. A structural comparison of CP 1 and CP 2 was done with compounds of same stoichiometry but crystallizing in different space groups. The band gap energies of CP 1 and CP 2 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 CP 2 offers a better anti‐bacterial, cytotoxicity and hemolytic activity than CP 1 .
