Assembly of 5-sulfosalicylic acid (H{sub 3}L) and d{sup 10} transition metal ions (Cd{sup II}, Ag{sup I}) with the neutral N-donor ligands produces five new complexes: [Cd{sub 2}(HL){sub 2}(4,4'-bipy){sub 3}]{sub n}.2nH{sub 2}O (1), {l_brace}[Cd{sub 2}(mu{sub 2}-HCO{sub 2}){sub 2}(4,4'-bipy){sub 2}(H{sub 2}O){sub 4}][Cd(HL){sub 2}(4,4'-bipy)(H{sub 2}O){sub 2}]{r_brace}{sub n} (2), {l_brace}[Cd(4,4'-bipy)(H{sub 2}O){sub 4}][HL].H{sub 2}O{r_brace}{sub n} (3), [Cd(HL)(dpp){sub 2}(H{sub 2}O)]{sub n}.4nH{sub 2}O (4), {l_brace}[Ag(4,4'-bipy)][Hhbs]{r_brace}{sub n} (5) (4,4'-bipy=4,4'-bipyridine, dpp=1,3-di(pyridin-4-yl)propane, H{sub 2}hbs=4-hydroxybenzenesulfonic acid, the decarboxylation product of H{sub 3}L). Complex 1 adopts a 5-connected 3D bilayer topology. Complex 2 has the herring-bone and ladder chain, which are extended to a 3D network via hydrogen bonding. In 3-4 complexes, 3 is a 3D supermolecular structure formed by polymeric chains and 2D network of HL{sup 2-}, while 4 gives the double-stranded chains. In 5, ladder arrays are stacked with the 2D networks of Hhbs{sup -} anions in an -ABAB- sequence. Complexes 1-4 display green luminescences in solid state at room temperature, while emission spectra of 3 and 4 show obvious blue-shifts at low temperature. - Graphical abstract: Reactions of 5-sulfosalicylic acid (H{sub 3}L) and d{sup 10} metal ions (Cd{sup II}, Ag{sup I}) produce five new complexes. Complexes 1-4 all display green luminescences at room temperature.
