The material structure described by NaC2 crystallizes in the orthorhombic Immm space group. Na(1) is bonded to eight equivalent C(1) atoms to form NaC8 hexagonal bipyramids that share corners with eight equivalent C(1)Na4C square pyramids and edges with twelve equivalent Na(1)C8 hexagonal bipyramids. C(1) is bonded to four equivalent Na(1) and one C(1) atom to form distorted CNa4C square pyramids that share corners with four equivalent Na(1)C8 hexagonal bipyramids, corners with sixteen equivalent C(1)Na4C square pyramids, and edges with six equivalent C(1)Na4C square pyramids. is represented by the CIF card [CIF]
