The material structure described by SrSi(OF3)2 crystallizes in the monoclinic P2_1/c space group. Sr(1) is bonded in a 8-coordinate geometry to one O(1), two equivalent O(2), one F(1), one F(2), one F(3), one F(4), and one F(6) atom. Si(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 two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Sr(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to two equivalent Sr(1) atoms. There are six inequivalent F sites. In the first F site, F(5) is bonded in a single-bond geometry to one Si(1) atom. In the second F site, F(6) is bonded in a bent 150 degrees geometry to one Sr(1) and one Si(1) atom. In the third F site, F(1) is bonded in a distorted linear geometry to one Sr(1) and one Si(1) atom. In the fourth F site, F(2) is bonded in a distorted linear geometry to one Sr(1) and one Si(1) atom. In the fifth F site, F(3) is bonded in a distorted bent 150 degrees geometry to one Sr(1) and one Si(1) atom. In the sixth F site, F(4) is bonded in a bent 150 degrees geometry to one Sr(1) and one Si(1) atom. is represented by the CIF card [CIF]
