KHfPdF7 crystallizes in the orthorhombic Pnna space group. K(1) is bonded in a 10-coordinate geometry to two equivalent F(1), two equivalent F(2), two equivalent F(4), and four equivalent F(3) atoms. Hf(1) is bonded to one F(2), two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form HfF7 pentagonal bipyramids that share corners with four equivalent Pd(1)F6 octahedra and  an edgeedge with one Pd(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 40-50°. Pd(1) is bonded to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form PdF6 octahedra that share corners with four equivalent Hf(1)F7 pentagonal bipyramids and  an edgeedge with one Hf(1)F7 pentagonal bipyramid. There are four inequivalent F sites. In the first F site, F(4) is bonded in a 3-coordinate geometry to one K(1), one Hf(1), and one Pd(1) atom. In the second F site, F(1) is bonded in a 2-coordinate geometry to one K(1), one Hf(1), and one Pd(1) atom. In the third F site, F(2) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Hf(1) atom. In the fourth F site, F(3) is bonded in a 4-coordinate geometry to two equivalent K(1), one Hf(1), and one Pd(1) atom.
