heal.abstractCrystals of a water soluble, potassium(I) complex with the heterocyclic thioamide; 2-mercapto-nicotinic acid (H2mna), of formula {[K(H2mna)2]+.[K(ΞΌ-OH)2]-.4H2O}n (1) were grown from the filtrate of the reaction between 2-mercapto-nicotinic acid with KOH in a molar ratio 1:1.5 in water. The complex has been characterized by elemental analysis, TG-DTA, 1H NMR and FT-IR spectroscopic techniques and X-ray powder diffraction. The single crystal structure of complex (1) has been determined by X-ray diffraction at ambient conditions. The polymeric structure of the complex is microporous, where water molecules are retained. The water molecules can be reversibly removed. The complex is ionic, containing [S-K+-S] linkages and an infinite ribbon of {[K(ΞΌ-OH)2]-}n as a counter anion. Strong hydrogen bonds and Ο€-Ο€ interactions stabilize the supramolecular architecture of the inorganic/metal-organic hybrid formed. Heating of (1) at 100 Β°C for 4 h forms the {[K(H2mna)2]+ .[K(ΞΌ-OH)2]-}n (2), which retains the framework structure although the coordinated water molecules were evacuated.en
