The structure described by CaC2 crystallizes in the orthorhombic Cmcm space group. Ca(1) is bonded in a 10-coordinate geometry to ten equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to five equivalent Ca(1) and two equivalent C(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
