Compositions of matter are provided wherein cis-platinum (II) and cis-palladium (II) moieties having amine substituents are bonded to anionic macromolecular entities. These compositions of matter may have improved solubility in the plasma and are effective antitrypanosomal and antitumor agents in mammals. Alternatively, the compositions of matter may be insoluble in water and particularly adapted for in situ implantation into tumerous masses.

Platinum and palladium complexes

A cathode for hydrogen evolution comprising a substrate stable in aqueous alkaline media having on the surface thereof a coating of particles of an AB.sub.N intermetallic, and optionally particles of a metal inert in the electrolyte, e.g., nickel, adhered to the substrate by sintered polytetrafluoroethylene or similar polymer.
