The material described by LaC2 crystallizes in the orthorhombic Immm space group. La(1) is bonded to eight equivalent C(1) atoms to form LaC8 hexagonal bipyramids that share corners with eight equivalent C(1)La4C square pyramids and edges with twelve equivalent La(1)C8 hexagonal bipyramids. C(1) is bonded to four equivalent La(1) and one C(1) atom to form distorted CLa4C square pyramids that share corners with four equivalent La(1)C8 hexagonal bipyramids, corners with sixteen equivalent C(1)La4C square pyramids, and edges with six equivalent C(1)La4C square pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
