Materials Data on K2PdC2 by Materials Project
K2PdC2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. K1+ is bonded in a trigonal planar geometry to three equivalent C2- atoms. All K–C bond lengths are 3.04 Å. Pd2+ is bonded in a linear geometry to two equivalent C2- atoms. Both Pd–C bond lengths are 2.01 Å. C2- is bonded to three equivalent K1+, one Pd2+, and one C2- atom to form distorted corner-sharing CK3PdC trigonal bipyramids. The C–C bond length is 1.27 Å.
