The material structure described by K3Na4BSi3F22 crystallizes in the orthorhombic Imm2 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to one F(8), one F(9), two equivalent F(1), two equivalent F(3), two equivalent F(6), and two equivalent F(7) atoms.
