The reaction of Pb(II) salts and mono- or disulfonates leads to the formation of eight new Pb(II)-mono/disulfonate complexes, [Pb(L1)(H₂O)]₂ (1), [Pb₄(L2)₂(AcO)₂]_n·5nH₂O (2), [Pb(L3)(H₂O)]₂ (3), [Pb(HL4)(H₂O)₂]_n·nH₂O (4), [Pb(HL5)(H₂O)₂]_n·2nH₂O (5), [Pb(H₂L6)(H₂O)]_n·nDMF·2nH₂O (6), [Pb₂(H₃L7)₄(H₂O)₆]·2H₂O (7) and [Pb(H₂L7)(H₂O)]_n·nH₂O (8) (H₂L1= 2-hydroxy-5-methyl-benzenesulfonic acid, H₃L2= 2-hydroxyl-5-methyl- 1,3-benzenedisulfonic acid, H₂L3= 2-hydroxy-5-nitro-benzenesulfonic acid, H₃L4= 2-hydroxyl-5-bromo-1,3- benzenedisulfonic acid, H₃L5= 2-hydroxyl-5-carboxyl-benzenesulfonic acid, H₄L6= 2,5-dihydroxyl-3-carboxyl- benzenesulfonic acid, H₄L7= 2,4-dihydroxyl-5-carboxyl-benzenesulfonic acid, DMF = N,N’-dimethyl-formamide, AcO^- = acetate), which have been characterized by elemental analysis, IR, TG, PL, powder and single-crystal X-ray diffraction. In view of the primary Pb–O bonds, these eight complexes exhibit diverse dinuclear (1, 3 and 7), helical chain (4), wave-like chain (5), linear chain (6), zigzag chain (8) and layer structure (2), in which the Pb(II) cations present different hemi-directed geometries. Taking the secondary Pb–O bonds into account, chain structure for complex 7, layer motifs for complexes 1 and 3–6, as well as 3-D framework for complex 8 are observed with Pb(II) cations showing more intricate holo-directed geometries. The various coordination modes of these seven different mono/disulfonate anions are responsible for the formation of these multiple structures. Furthermore, the introduction of hydroxyl and carboxyl groups increases the coordination ability of sulfonate to the p-block metal cation. Luminescent analyses indicate that complex 7 presents purple emission at 395 nm at room temperature.
