Lithium hydrogen iodofumarate monohydrate

H. Billetter, I. Pantenburg and U. Ruschewitz

Abstract: Yellow crystals of the title compound, poly[[aqualithium(I)]-₃-iodofumarato], [Li(HOOC-CH=CI-COO)(H₂O)]_n, crystallized unexpectedly from an aqueous solution containing acetylenedicarboxylic acid and LiI. The lithium cation is coordinated tetrahedrally by four O atoms of three iodofumarate anions and one water molecule. These tetrahedra are connected such that a layered coordination polymer is formed.
