The material structure described by K2PdSe10 crystallizes in the tetragonal I-42d space group. K(1) is bonded in a 5-coordinate geometry to one Se(1), one Se(3), one Se(4), two equivalent Se(2), and two equivalent Se(5) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a rectangular see-saw-like geometry to four equivalent Se(5) atoms. In the second Pd site, Pd(2) is bonded in a rectangular see-saw-like geometry to four equivalent Se(2) atoms. There are five inequivalent Se sites. In the first Se site, Se(5) is bonded in a 4-coordinate geometry to two equivalent K(1), one Pd(1), and one Se(4) atom. In the second Se site, Se(1) is bonded in a distorted T-shaped geometry to one K(1), one Se(2), and one Se(3) atom. In the third Se site, Se(2) is bonded in a 4-coordinate geometry to two equivalent K(1), one Pd(2), and one Se(1) atom. In the fourth Se site, Se(3) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one Se(1), and one Se(3) atom. In the fifth Se site, Se(4) is bonded in a distorted trigonal non-coplanar geometry to one K(1), one Se(4), and one Se(5) atom. is represented by the CIF card [CIF]
