SrTaF7 crystallizes in the monoclinic P2_1/m space group. Sr(1) is bonded in a 10-coordinate geometry to one F(1), one F(3), two equivalent F(2), two equivalent F(5), and four equivalent F(4) atoms. Ta(1) is bonded in a 7-coordinate geometry to one F(1), one F(3), one F(5), two equivalent F(2), and two equivalent F(4) atoms. There are five inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to one Sr(1) and one Ta(1) atom. In the second F site, F(2) is bonded in a distorted linear geometry to one Sr(1) and one Ta(1) atom. In the third F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Ta(1) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Ta(1) atom. In the fifth F site, F(5) is bonded in a 3-coordinate geometry to two equivalent Sr(1) and one Ta(1) atom.
