Abstract
The structure originally reported as poly[[μ7-L-cysteato(2−)]disodium], [Na2(C3H5NO5S)]n[Liu (2002).Acta Cryst. E67, m1346–m1347], has been redetermined with one of the sodium atoms replaced with a water molecule and an additional proton attached to the amine group, resulting in the revised formula [Na{CO2CH(CH2SO3)NH3}(H2O)]n. The agreement index,wR, has been reduced from 0.159 to 0.087 and the global instability index from 0.56 vu (valence units) to the acceptable value of 0.11 vu.
