The material structure described by SmHfF7 crystallizes in the monoclinic P2_1 space group. Sm(1) is bonded in a 8-coordinate geometry to one F(2), one F(3), one F(4), one F(5), one F(6), one F(7), and two equivalent F(1) atoms. Hf(1) is bonded in an octahedral geometry to one F(2), one F(3), one F(4), one F(5), one F(6), and one F(7) atom. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent Sm(1) atoms. In the second F site, F(2) is bonded in a distorted linear geometry to one Sm(1) and one Hf(1) atom. In the third F site, F(3) is bonded in a linear geometry to one Sm(1) and one Hf(1) atom. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Sm(1) and one Hf(1) atom. In the fifth F site, F(5) is bonded in a linear geometry to one Sm(1) and one Hf(1) atom. In the sixth F site, F(6) is bonded in a distorted bent 150 degrees geometry to one Sm(1) and one Hf(1) atom. In the seventh F site, F(7) is bonded in a bent 150 degrees geometry to one Sm(1) and one Hf(1) atom. is represented by the CIF card [CIF]
