Materials Data on ThCN by Materials Project
NCTh crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Th4+ is bonded in a 7-coordinate geometry to three equivalent C2- and four equivalent N2- atoms. There are two shorter (2.82 Å) and one longer (2.85 Å) Th–C bond lengths. There are a spread of Th–N bond distances ranging from 2.36–2.39 Å. C2- is bonded in a rectangular see-saw-like geometry to three equivalent Th4+ and one C2- atom. The C–C bond length is 1.26 Å. N2- is bonded to four equivalent Th4+ atoms to form a mixture of edge and corner-sharing NTh4 tetrahedra.
