The structure described by BaC2 crystallizes in the trigonal R-3m space group. Ba(1) is bonded in a body-centered cubic geometry to eight equivalent C(1) atoms. C(1) is bonded to four equivalent Ba(1) and one C(1) atom to form a mixture of distorted edge and corner-sharing CBa4C trigonal bipyramids. is represented by the CIF card [CIF]
