Poly[di-μ-aqua-μ4-(pyrazine-2,5-dicarboxylato)-dilithium(I)]

In the title coordination polymer, [Li2(C6H2N2O2)(H2O)2]n the pyrazine-2,5-dicarboxylate dianionic ligand bridges two symmetry-independent Li+ ions using both its N,O-chelating sites. The carboxylate O atom of one of them also bridges to another Li+ ion, while the second O atom of this group is bond...
