AbstractThe crystal structure of mercury(II)chromate hemihydrate, HgCrOThe mercury atom is bonded only to two oxygen atoms, each belonging to a separate Chromate tetrahedron, at the distances 2.055(2) and 2.064(2) Å, the angle O–Hg–O being 179.95(5)°. As each Chromate group is bonded to two mercury atoms, fundamental building elements of the structure are endless chains of the composition (HgCrOIn the water molecule the distances O(W)–H (2 × ) and H–H are 0.945(4) and 1.487(6) Å respectively. The angle H–O(W)–H is 103.7(4)°. In the hydrogen bonds the distance O(W)–H…O between water and Chromate oxygen atoms is 2.961(2) Å with a distance H…O of 2.133(4) Å and an angle O(W)–H…O of 145.6(3)°.
