Zinc(II) sulfate tetrahydrate

A. J. Blake, P. A. Cooke, P. Hubberstey and C. L. Sampson

Abstract: The title compound crystallizes as centrosymmetric [Zn(₂-SO₄)(H₂O)₄]₂ dimers. The six-coordinate geometry of the zinc(II) centre comprises four water molecules and two cis-located bridging sulfate anions in a distorted octahedral array within which the Zn-O interatomic distances and O-Zn-O interatomic angles fall into the narrow ranges 2.080  (8)-2.125  (7)  Å and 83.7  (3)-96.7  (3)°, respectively. Strong O-HO hydrogen bonds involving seven of the eight water-H atoms link the dimers to form a three-dimensional body-centred network.
