✦ Synopsis

In recent years considerable interest has been expressed in soluble, polynuclear transition metal complexes. A number of soluble complexes containing a few metal centers have been reported [l], but only one high molecular weight complex, an iron/hydroxy/ nitrate compound, has been described [2][3][4]. It was shown to have a spheroidal shape. We wish to report the preparation and characterization of a soluble, high molecular weight polymeric transition metal complex containing Ni*+ and Sphenyltetrazolate which has a rigid, rod-like shape in solution. We believe this to be the first report of a soluble, extended structure polymer containing transition metal ions in its backbone.

When aqueous solutions of Ni(NO,)* -6H2O and sodium Sphenyltetrazolate*** (hereinafter NaT) are mixed together so that the final concentration of NaT ranges from near its maximum solubility of 0.6 M to less than low4 M and the T-to Ni*+ ratio ranges from 0.1 to 20, a blue precipitate of NiT2-3H20 forms immediately.
