The material structure described by KYb2F7 crystallizes in the monoclinic P2 space group. K(1) is bonded in a distorted q6 geometry to two equivalent F(3), four equivalent F(1), and four equivalent F(2) atoms. Yb(1) is bonded to one F(4), two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form a mixture of edge and corner-sharing YbF7 pentagonal bipyramids. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted water-like geometry to two equivalent K(1) and two equivalent Yb(1) atoms. In the second F site, F(2) is bonded in a 4-coordinate geometry to two equivalent K(1) and two equivalent Yb(1) atoms. In the third F site, F(3) is bonded in a distorted T-shaped geometry to one K(1) and two equivalent Yb(1) atoms. In the fourth F site, F(4) is bonded in a linear geometry to two equivalent Yb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
