Na2PdC2 crystallizes in the trigonal P-3m1 space group. Na(1) is bonded in a 6-coordinate geometry to three equivalent Pd(1) and three equivalent C(1) atoms. Pd(1) is bonded in a distorted linear geometry to six equivalent Na(1) and two equivalent C(1) atoms. C(1) is bonded to three equivalent Na(1), one Pd(1), and one C(1) atom to form distorted corner-sharing CNa3PdC trigonal bipyramids.
