Compounds of glycine with metal sulfates and thiosulfates: glycine cobalt sulfate pentahydrate, glycine sodium thiosulfate dihydrate and glycine potassium thiosulfate

M. Fleck and L. Bohatý

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-₃-glycinato-di-₄-thiosulfato-tetrasodium(I)], [Na₄(C₂H₅NO₂)(S₂O₃)₂(H₂O)₂]_n, (II), and poly[₂-glycinato-₄-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.

Formula: [Co(H₂O)₆][Co(C₂H₅NO₂)₂(H₂O)₄](SO₄)₂, [Na₄(C₂H₅NO₂)(S₂O₃)₂(H₂O)₂]_n and [K₂(C₂H₅NO₂)(S₂O₃)]_n
