Materials Data on SrSi(OF3)2 by Materials Project
SrSi(OF3)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr is bonded in a 5-coordinate geometry to three O and five F atoms. There are a spread of Sr–O bond distances ranging from 2.80–2.95 Å. There are a spread of Sr–F bond distances ranging from 2.41–2.51 Å. Si is bonded in an octahedral geometry to six F atoms. There are a spread of Si–F bond distances ranging from 1.70–1.73 Å. There are two inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Sr atom. In the second O site, O is bonded in a bent 120 degrees geometry to two equivalent Sr atoms. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Si atom. In the second F site, F is bonded in a bent 150 degrees geometry to one Sr and one Si atom. In the third F site, F is bonded in a distorted linear geometry to one Sr and one Si atom. In the fourth F site, F is bonded in a distorted linear geometry to one Sr and one Si atom. In the fifth F site, F is bonded in a distorted bent 150 degrees geometry to one Sr and one Si atom. In the sixth F site, F is bonded in a bent 150 degrees geometry to one Sr and one Si atom.
