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 .beta.-hydroxy-.alpha.,.gamma.-diamines. The above are electrical semiconductors. Such polymers containing platinum have a biological activity.
