Materials Data on KAu(CN)2 by Materials Project
KAu(CN)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded to six equivalent N3- atoms to form edge-sharing KN6 octahedra. There are three shorter (2.83 Å) and three longer (2.90 Å) K–N bond lengths. In the second K1+ site, K1+ is bonded to six equivalent N3- atoms to form edge-sharing KN6 octahedra. All K–N bond lengths are 2.85 Å. Au1- is bonded in a linear geometry to two equivalent C3+ atoms. Both Au–C bond lengths are 1.99 Å. C3+ is bonded in a distorted single-bond geometry to one Au1- and one N3- atom. The C–N bond length is 1.17 Å. N3- is bonded to three K1+ and one C3+ atom to form a mixture of distorted edge and corner-sharing NK3C tetrahedra.
