Materials Data on FeSn2(CN)6 by Materials Project

Sn2Fe(CN)6 crystallizes in the trigonal P-3 space group. The structure is two-dimensional and consists of one Sn2Fe(CN)6 sheet oriented in the (0, 0, 1) direction. Fe2+ is bonded in an octahedral geometry to six equivalent C+1.33+ atoms. All Fe–C bond lengths are 1.88 Å. Sn4+ is bonded in a distorted T-shaped geometry to three equivalent N3- atoms. All Sn–N bond lengths are 2.26 Å. C+1.33+ is bonded in a linear geometry to one Fe2+ and one N3- atom. The C–N bond length is 1.18 Å. N3- is bonded in a bent 150 degrees geometry to one Sn4+ and one C+1.33+ atom.
