Abstract

Single crystals of dilithium-acetylenedicarboxylatedihydrate, Li(2)ADC center dot 2H(2)O (1), were isolated from a solid product formed by isothermal evaporation of an aqueous solution of LiOH und acetylenedicarboxylic acid (H2ADC). 1 crystallizes in the triclinic space group P (1) over bar with Z = 2. LiO4 tetrahedra are interconnected by ADC(2-) anions and water molecules to form a 3D polymeric structure. Coupled TGA and DTA measurements show that 1 loses its two water molecules above 100 degrees C. Heating a polycrystalline sample of 1 at 140 degrees C for 2 h in an argon atmosphere leads to a significant change of the powder diffraction pattern indicating the formation of the new anhydrous coordination polymer dilithium-acetylenedicarboxylate, Li(2)ADC (2). Its crystal structure was solved and refined from X-ray powder diffraction data. 2 crystallizes in the orthorhombic space group Fddd (Z = 8). LiO4 tetrahedra are interconnected by ADC(2-) anions to form a 3D polymeric structure.
