Abstract

In the crystal structures of the title compounds, hexaaquacobalt(II) tetraaquadiglycinatocobalt(II) bis(sulfate), [Co(H2O)6][Co(C2H5NO2)2(H2O)4](SO4)2, (I), poly[diaqua-mu3-glycinato-di-mu4-thiosulfato-tetrasodium(I)], [Na4(C2H5NO2)(S2O3)2(H2O)2]n, (II), and poly[mu2-glycinato-mu4-thiosulfato-dipotassium(I)], [K2(C2H5NO2)(S2O3)]n, (III), all atoms are located on general positions, except the Co atoms in (I), which are located on inversion centres. In (I), hydrogen bonds play an important role, while the alkali thiosulfate compounds are characterized by three-dimensional frameworks of polyhedra. Relations to other compounds of glycine and metal sulfates are commented on.
