Two Coordination Polymers of Ag(I) with 5-Sulfosalicylic Acid

The reactions of AgNO3 with Na2L and Mg(HL)2 (H2L = 5-sulfosalicylic acid) gave two luminescent
coordination polymers:  Ag2L(H2O) (1) and [Ag2(HL)2(H2O)3]H2O (2), respectively. 1 crystallizes in the monoclinic
space group P2/n, with a = 7.489(2), b = 16.237(3), c = 8.222(2) Å, β = 92.90(3)°, V = 998.5(3) Å3, Z = 4. Compound
1 is the first silver carboxylate-sulfonate with an extended three-dimensional structure, a framework composed of
four kinds of crystallographically unique silver atoms and organic species with three different functional groups,
carboxylic, hydroxyl, and sulfonic, each coordinated to the silver atoms. 2 crystallizes in the triclinic space group
P1̄, with a = 8.307(2), b = 11.246(2), c = 12.590(3) Å, α =112.68(3), β = 97.66(3), γ = 95.51(3)°, V = 1061.6(4) Å3,
Z = 2. In 2, silver ions are bridged by sulfonate groups to form one-dimensional chains, and each chain is connected
to the two neighboring chains through the coordination of the carbonyl oxygen atoms to the silver ions of the
neighboring polymeric chain to form a two-dimensional network. The luminescent properties of the two compounds
are also discussed.
