Materials Data on Bi(PdO2)2 by Materials Project

BiPd2O4 crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one BiPd2O4 sheet oriented in the (0, 0, 1) direction. Pd3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Pd–O bond lengths are 2.01 Å. Bi2+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All Bi–O bond lengths are 2.25 Å. O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Pd3+ and one Bi2+ atom.

Materials Data on Bi2PdO4 by Materials Project

PdBi2O4 crystallizes in the tetragonal P4/ncc space group. The structure is three-dimensional. Pd2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Pd–O bond lengths are 2.05 Å. Bi3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing BiO6 pentagonal pyramids. There are a spread of Bi–O bond distances ranging from 2.21–2.74 Å. O2- is bonded in a 4-coordinate geometry to one Pd2+ and three equivalent Bi3+ atoms.

Materials Data on Bi2PdO4 by Materials Project

PdBi2O4 crystallizes in the tetragonal I4cm space group. The structure is three-dimensional. Pd2+ is bonded in a rectangular see-saw-like geometry to four equivalent O2- atoms. All Pd–O bond lengths are 2.04 Å. Bi3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. There are two shorter (2.24 Å) and two longer (2.26 Å) Bi–O bond lengths. O2- is bonded in a 3-coordinate geometry to one Pd2+ and two equivalent Bi3+ atoms.
