The combination of zinc (II) with phytic acid has been investigated under a variety of reaction conditions. With the P:Zn ratios used, i.e. 1:1 or 6:1, in the preparations elemental analyses of the isolated products indicated P:Zn ratios of either 1, 1.2 or 1.5 dependent upon the initial P:Zn ratios and the various bases and salts used in the preparations. Of the total number of experiments carried out elemental analyses indicated that only about 25% of the isolated complexes had stoichiometric atomic ratios.
