The material described by EuSnF7 crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 8-coordinate geometry to one F(1), one F(2), one F(3), one F(4), one F(5), one F(6), and two equivalent F(7) atoms. Sn(1) is bonded in an octahedral geometry to one F(1), one F(2), one F(3), one F(4), one F(5), and one F(6) atom. There are seven inequivalent F sites. In the first F site, F(7) is bonded in a bent 150 degrees geometry to two equivalent Eu(1) atoms. In the second F site, F(1) is bonded in a bent 150 degrees geometry to one Eu(1) and one Sn(1) atom. In the third F site, F(2) is bonded in a bent 150 degrees geometry to one Eu(1) and one Sn(1) atom. In the fourth F site, F(3) is bonded in a linear geometry to one Eu(1) and one Sn(1) atom. In the fifth F site, F(4) is bonded in a distorted bent 150 degrees geometry to one Eu(1) and one Sn(1) atom. In the sixth F site, F(5) is bonded in a bent 150 degrees geometry to one Eu(1) and one Sn(1) atom. In the seventh F site, F(6) is bonded in a bent 150 degrees geometry to one Eu(1) and one Sn(1) atom. is represented by the CIF card [CIF]
