Materials Data on KTl(CN)4 by Materials Project
KTl(CN)4 crystallizes in the tetragonal I4_1/a space group. The structure is three-dimensional and consists of two KTl(CN)4 frameworks. K1+ is bonded in a tetrahedral geometry to four equivalent N3- atoms. All K–N bond lengths are 2.90 Å. Tl1+ is bonded in a tetrahedral geometry to four equivalent C+2.50+ atoms. All Tl–C bond lengths are 2.21 Å. C+2.50+ is bonded in a linear geometry to one Tl1+ and one N3- atom. The C–N bond length is 1.17 Å. N3- is bonded in a distorted bent 120 degrees geometry to one K1+ and one C+2.50+ atom.
