Materials Data on Hg2P4PdO8 by Materials Project

PdHg2P4O8 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Pd2+ is bonded in a 4-coordinate geometry to four equivalent P3+ atoms. All Pd–P bond lengths are 2.32 Å. Hg1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.08 Å) and two longer (2.69 Å) Hg–O bond lengths. P3+ is bonded in a bent 120 degrees geometry to one Pd2+ and two O2- atoms. There is one shorter (1.49 Å) and one longer (1.56 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Hg1+ and one P3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Hg1+ and one P3+ atom.

Materials Data on HgP2PdO7 by Materials Project

PdHgP2O7 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Pd2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.03 Å) and two longer (2.06 Å) Pd–O bond lengths. Hg2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Hg–O bond distances ranging from 2.10–2.97 Å. P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.53–1.63 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Pd2+, one Hg2+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent P5+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Hg2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Pd2+, one Hg2+, and one P5+ atom.

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.
