Materials Data on FePb2(CN)6 by Materials Project
Pb2Fe(CN)6 crystallizes in the trigonal P-3 space group. The structure is two-dimensional and consists of one iron molecule and one Pb(CN)3 sheet oriented in the (0, 0, 1) direction. In the Pb(CN)3 sheet, Pb2+ is bonded to six equivalent N3- atoms to form distorted edge-sharing PbN6 octahedra. There are three shorter (2.47 Å) and three longer (2.88 Å) Pb–N bond lengths. C+1.83+ is bonded in a distorted single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. N3- is bonded in a distorted single-bond geometry to two equivalent Pb2+ and one C+1.83+ atom.
