Materials Data on HgP2(PdO4)2 by Materials Project
HgP2(PdO4)2 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.05 Å) and two longer (2.06 Å) Pd–O bond lengths. Hg2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.38 Å) and four longer (2.70 Å) Hg–O bond lengths. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.55 Å) and two longer (1.57 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Pd2+, one Hg2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Pd2+, one Hg2+, and one P5+ atom.
