Materials Data on H2Pd(S2O7)2 by Materials Project
PdH2(S2O7)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Pd2+ is bonded to six O2- atoms to form PdO6 octahedra that share corners with six SO4 tetrahedra. There are a spread of Pd–O bond distances ranging from 2.24–2.26 Å. H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.69 Å) H–O bond length. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent PdO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedra tilt angles range from 42–45°. There are a spread of S–O bond distances ranging from 1.44–1.70 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one PdO6 octahedra and a cornercorner with one SO4 tetrahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of S–O bond distances ranging from 1.43–1.61 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Pd2+ and one S6+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Pd2+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one H1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Pd2+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one H1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S6+ atom.
