Materials Data on SnH4C2NO4F by Materials Project

NH4SnC2O4F crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of four ammonium molecules and two SnC2O4F ribbons oriented in the (1, 0, 0) direction. In each SnC2O4F ribbon, Sn2+ is bonded in a 5-coordinate geometry to four O2- and one F1- atom. There are two shorter (2.29 Å) and two longer (2.67 Å) Sn–O bond lengths. The Sn–F bond length is 2.11 Å. There are two inequivalent C3+ sites. In the first C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.24 Å) and one longer (1.30 Å) C–O bond length. In the second C3+ site, C3+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.25 Å) and one longer (1.29 Å) C–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Sn2+ and one C3+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one C3+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sn2+ and one C3+ atom. F1- is bonded in a single-bond geometry to one Sn2+ atom.

Materials Data on Sn2H10C4N2O9F2 by Materials Project

(NH4)2(SnC2O4F)2H2O crystallizes in the monoclinic P2_1/c space group. The structure is one-dimensional and consists of eight ammonium molecules; four water molecules; and two SnC2O4F ribbons oriented in the (2, 0, 1) direction. In each SnC2O4F ribbon, there are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bonded in a 5-coordinate geometry to four O2- and one F1- atom. There are a spread of Sn–O bond distances ranging from 2.31–2.59 Å. The Sn–F bond length is 2.14 Å. In the second Sn4+ site, Sn4+ is bonded in a 5-coordinate geometry to four O2- and one F1- atom. There are a spread of Sn–O bond distances ranging from 2.34–2.65 Å. The Sn–F bond length is 2.09 Å. There are four inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. In the second C2+ site, C2+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. In the third C2+ site, C2+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. In the fourth C2+ site, C2+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.28 Å) C–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Sn4+ and one C2+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one Sn4+ and one C2+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one Sn4+ and one C2+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one Sn4+ and one C2+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one Sn4+ and one C2+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Sn4+ and one C2+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Sn4+ and one C2+ atom. In the eighth O2- site, O2- is bonded in a single-bond geometry to one Sn4+ and one C2+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sn4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sn4+ atom.
