A novel two-dimensional self-assembly network formulated as [K(TSSB)](n) (TSSB = taurine-salicylaldehyde Schiff base) has been synthesized via the reaction of salicylaldehyde with taurine at the presence of potassium hydroxide in water-methanol solution, and was structurally characterized by elemental analysis, IR, UV-VIS spectra and X-ray diffraction. It crystallizes in the monoclinic system, space group P2(1)/c with a = 20.245(3), b = 7.2905(9), c = 7.5458(10) angstrom, beta = 94.1920(10)degrees, V = 1110.8(2) angstrom(3), M(r) = 267.34, Z = 4, D(c) = 1.599 g/cm(3), mu(MoK alpha) = 0.663 mm(-1) and F(000) = 552. The units of K[TSSB] are linked into a one-dimensional double chain structure via the sulfonic groups from the taurine-salicylaldelyde Schiff base, and such chains are further extended through O-K-O bond interactions resulting in a two-dimensional supramolecular architecture. In the complex, the K(I) ion displays a slightly distorted dodecahedral geometry with an eight-coordination number.
