BeYNF6 crystallizes in the monoclinic P2_1/m space group. Be(1) is bonded in a tetrahedral geometry to one F(2), one F(4), and two equivalent F(1) atoms. Y(1) is bonded in a 8-coordinate geometry to one F(2), one F(4), two equivalent F(1), and four equivalent F(3) atoms. N(1) is bonded in an L-shaped geometry to two equivalent F(3) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to one Be(1) and one Y(1) atom. In the second F site, F(2) is bonded in a linear geometry to one Be(1) and one Y(1) atom. In the third F site, F(3) is bonded in a distorted trigonal planar geometry to two equivalent Y(1) and one N(1) atom. In the fourth F site, F(4) is bonded in a distorted bent 150 degrees geometry to one Be(1) and one Y(1) atom.
