Materials Data on K2PdBr4 by Materials Project
K2PdBr4 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight equivalent Br1- atoms. All K–Br bond lengths are 3.48 Å. Pd2+ is bonded in a square co-planar geometry to four equivalent Br1- atoms. All Pd–Br bond lengths are 2.48 Å. Br1- is bonded to four equivalent K1+ and one Pd2+ atom to form a mixture of distorted corner, edge, and face-sharing BrK4Pd square pyramids.
