The material structure described by PaC2 crystallizes in the tetragonal I4/mmm space group. Pa(1) is bonded in a 10-coordinate geometry to ten equivalent C(1) atoms. C(1) is bonded in a 6-coordinate geometry to five equivalent Pa(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
