Triplatinum Tetraoxides

Most metal chain complexes involve divalent and partially oxidized square-planar complexes of Ni, Pd, and Pth Examples include the tetracyanoplatinates , bis(oxalato)platinates , bisglyoximato and several complexes containing chelating 7t-conjugated ligands . Nonstoichiometric triplatinum tetraoxides are discussed independently. 

The insoluble solid triplatinum tetraoxides exhibit metal chain structures with nonstoichiometric amounts of cations. They are prepared by pyrolysis, e.g. ...
