The compound described by BaC2 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded to eight equivalent C(1) atoms to form distorted edge-sharing BaC8 hexagonal bipyramids. C(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1) and one C(1) atom. is represented by the CIF file [CIF]
