Correlation between the formal partial oxidation states observed in the one-dimensional platinum metal complexes and the resonating valence bond theory of metals
Recently, a number of the partially oxidized one-dimensional conducting salts of the tetracyanoplatinate and bis(oxalato)platinate variety have been characterized. These contain chains of partially oxidized metal atoms in which the metal--metal bonding appears to have much in common with bonding in pure metals except that it is one dimensional. Structural and chemical data for these materials give support to two observations: the concept of a single partial oxidation state which is resonance stabilized in different anionic and cationic deficient systems; a correlation between oxidation state and metal--metal distance. It is proposed that a basis for understanding these observations is provided by the resonating valence bond theory. The following areas are discussed: the relationship of oxidation state and bond number, a bond number vs. metal--metal distance equation which accurately fits all experimentally characterized partially oxidized Pt l-D complexes, and evidence that Pt--Pt bond formation in the l-D chains is resonance energy stabilized producing equivalent metal--metal distances.
