The material described by K3Pd2O4 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the second K site, K(2) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. In the second Pd site, Pd(2) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to one K(2), three equivalent K(1), one Pd(1), and one Pd(2) atom to form a mixture of distorted edge, corner, and face-sharing OK4Pd2 octahedra. The corner-sharing octahedral tilt angles range from 0-71°. is represented by the Crystallographic Information File (CIF) [CIF]
