This paper reviews the properties of complex forming ion exchangers (C
FIE) and those of the ion exchanger complexes (IEC) with transition me
tal ions. It is mainly dedicated to the development of a novel approac
h in characterizing TEC which is based on the consideration of CFIE as
three-dimensional polymeric ligands. The approach is illustrated by t
he results obtained by studying the specificity of complex formation w
ith CFIE of different types, the structure, properties and possible ap
plications of TEC as anion exchangers, as electron exchangers, as liga
nd exchangers and some others. A particular attention is paid to the t
ailored synthesis of the IEC with desired properties such as the compo
sition of the statistically-average coordination center, the distribut
ion of metal ions along the polymer chain, etc., and to their applicat
ion as catalysts which combine the high selectivity and activity of th
e homogenous metal-complex catalysts with the technological convenienc
e of the heterogeneous ones. The application of the IEC as convenient
models for bio-catalysts (metalloenzymes) is also discussed.
