Materials Data on Cd2Fe(CN)6 by Materials Project
Fe(Cd(CN)3)2 crystallizes in the trigonal P-3 space group. The structure is two-dimensional and consists of one iron molecule and one Cd(CN)3 sheet oriented in the (0, 0, 1) direction. In the Cd(CN)3 sheet, Cd2+ is bonded to six equivalent N3- atoms to form edge-sharing CdN6 octahedra. There are three shorter (2.38 Å) and three longer (2.39 Å) Cd–N bond lengths. C+1.83+ is bonded in a distorted single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. N3- is bonded in a distorted trigonal planar geometry to two equivalent Cd2+ and one C+1.83+ atom.
