Materials Data on HgH12(ClO7)2 by Materials Project
Hg(H2O)6(ClO4)2 crystallizes in the trigonal P-3m1 space group. The structure is zero-dimensional and consists of two ClO4 clusters and one Hg(H2O)6 cluster. In each ClO4 cluster, there are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.47 Å. In the second O site, O is bonded in a single-bond geometry to one Cl atom. The O–Cl bond length is 1.45 Å. Cl is bonded in a tetrahedral geometry to four O atoms. In the Hg(H2O)6 cluster, Hg is bonded in an octahedral geometry to six equivalent O atoms. All Hg–O bond lengths are 2.40 Å. H is bonded in a single-bond geometry to one O atom. The H–O bond length is 0.98 Å. O is bonded in a distorted water-like geometry to one Hg and two equivalent H atoms.
