Zirconium(IV) sulfate

Zirconium(IV) sulfate is the name for a family of inorganic compounds with the formula Zr(SO4)2(H2O)n where n = 0, 4, 5, or 7.

At least some members of the series contain oxo ligands since zirconyl (ZrO2+) is pervasive.

These compounds are white or colorless solids that often are soluble in water.

[2] These compounds adopt complex structures featuring 7- and 8-coordinated Zr centres.

[3][4] Zirconium sulfate is used in tanning white leather, as a catalyst support, to precipitate proteins and amino acids, and as a pigment stabilizer.
