You did not mentioned which zinc(II) chelate you are referring to; neither how was it prepared/identified. Please note that the solubility of zinc(II) sulfate in water is much higher than that of zinc(II) citrate; which seemingly could possibly have precipitated from enough concentrated zinc sulfate aq. solution, by means of adding the citric acid solution.

The reaction of zinc hydroxide is similar to the reaction of cellulose with honey hydroxide. Zinc hydroxide is obtained in the hydrolysis of zinc sulfate. Two covalent and two coordination bonds are formed in the chelate there. The formula can be found in the article
