The material structure described by K3UF3 crystallizes in the triclinic P1 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a bent 120 degrees geometry to one F(1) and one F(3) atom. In the second K site, K(2) is bonded in a distorted T-shaped geometry to one F(1), one F(2), and one F(3) atom. In the third K site, K(3) is bonded in a distorted T-shaped geometry to one F(1), one F(2), and one F(3) atom. U(1) is bonded in a distorted T-shaped geometry to one F(1), one F(2), and one F(3) atom. There are three inequivalent F sites. In the first F site, F(1) is bonded to one K(1), one K(2), one K(3), and one U(1) atom to form corner-sharing FK3U tetrahedra. In the second F site, F(2) is bonded in a distorted T-shaped geometry to one K(2), one K(3), and one U(1) atom. In the third F site, F(3) is bonded to one K(1), one K(2), one K(3), and one U(1) atom to form corner-sharing FK3U tetrahedra. is represented by the CIF card [CIF]
