Abstract

There are provided metal containing polymeric coordination compounds which are prepared by a process which comprises reacting metal salts with polydentate ligand molecules obtained by the condensation of aromatic dialdehydes with β-hydroxy-α,γ-diamines. The above are electrical semiconductors. Such polymers containing platinum have a biological activity.

Claims

1. Polymeric compounds of formulas (I) and (II) ##STR5## wherein R designates a bivalent aromatic hydrocarbon group,

R₁ and R₂ designate monovalent hydrocarbon groups,

M is a metal cation capable of forming coordination bonds with imino- and amino-nitrogen atoms,

A and A¹ are anions acting as counter ions of M,

n is zero or an integer depending on the valency of M.

2. A polymeric compound according to claim 1 where M is selected from Ag, Zn, Cu, Co, Ni, Mn, Fe, Ti, Pt, Sb and Pb ions.

3. A polymeric compound according to claim 1, wherein the polymer is the reaction product of an aromatic dialdehyde with an β

-hydroxy-α

,γ

-diamine which is subsequently reacted with an inorganic salt.

4. A polymeric compound according to claim 1, being the reaction product of terephthalaldehyde and 1-amino-2-hydroxy-3,N,N-butyl-benzylaminopropane and the subsequent reaction of the thus obtained intermediate with a suitable salt.

5. A process for the production of polymers of Formula I and II defined in claim 1 which comprises:

a. Condensing an aromatic dialdehyde with a β

-hydroxy-α

,γ

-diamine to form the "monomeric" polydentate ligand;

b. preparing a solution of the "monomeric" polydentate ligand in an organic solvent, preferably an aprotic volatile solvent, such as toluene or chloroform;

c. dissolving a chosen inorganic salt in the "monomeric" polydentate ligand solution;

d. evaporating of the solvent from the thus obtained solution to result in a solid product in the form of a thin layer, powder or flakes.

6. A process according to claim 5 wherein the product is baked at a temperature of from 100°

to 150°

C. to modify its solubility and physical properties.

7.
