Materials Data on KAgC2 by Materials Project
KAgC2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. K1+ is bonded to eight equivalent C1- atoms to form a mixture of edge and face-sharing KC8 hexagonal bipyramids. All K–C bond lengths are 3.13 Å. Ag1+ is bonded in a linear geometry to two equivalent C1- atoms. Both Ag–C bond lengths are 2.05 Å. C1- is bonded in a distorted linear geometry to four equivalent K1+, one Ag1+, and one C1- atom. The C–C bond length is 1.25 Å.
