“…On the other hand, in the case of Ca II , ionic coordination with participation of the sulfo group of the Liduronate and the sulfo group at the C(6 H ) atom of the D-glucosamine residue 351 has been suggested. 350 In the presence of excess Ca II , neighbouring chains of the polymer are linked according to the `egg box' pattern (Section II.1). 345 The complexation hypothesis is supported by the series of the efficiency of binding of smetals with heparin 343, 352 (Na + < K + < Mg 2+ < Sr 2+ < Ba 2+ < Ca 2+ ), since, according to the condensation theory, 78 the most efficient binding would be observed for the Mg 2+ cation characterised by the maximum charge density.…”

Data on the interaction of natural carbohydrates (mono-, oligo-, and poly-saccharides, amino sugars, and natural organic acids of carbohydrate origin) with metal cations are surveyed and described systematically. The structural diversity of carbohydrate metal complexes, caused by some specific features of carbohydrates as ligands, is demonstrated. The influence of complex formation on the chemical properties of carbohydrates is discussed. It is shown that the formation of metal complexes plays an important role in the configurational and conformational analysis of carbohydrates. The practical significance of the coordination interaction in the series of carbohydrate ligands is demonstrated. The bibliography includes 571 references.

High-yield synthetic routes to trinuclear complexes of the type [M(OsA3)2] (M = Mg, Ca, Sr or Ba; A = anion of arylazo oxime) by reaction of NaEOsA 3] and M(C104) 1, or of [HOsA3] with MCO 3, are described. The new complexes have been characterized on the basis of spectroscopic and physico-chemical results. The alkaline earth metal ions are held in an 0 6 matrix of two facial I-OsA3] units, each behaving as a tridentate (O, O, O) ligand. Quantitative transport of one equivalent of M 2 + from the aqueous to the organic (CHzC12) phase can be achieved with two equivalents of [OsA3]-. When the aqueous phase is acidified with two tool of H+, [M(OsA3)e] decomposes into M 2+ and [HOsA3], and M 2+ returns to this phase in its free state.
