The crystal structure described by Gd2C3 is Plutonium carbide structured and crystallizes in the cubic I-43d space group. Gd(1) is bonded in a 6-coordinate geometry to six equivalent C(1) atoms. C(1) is bonded to four equivalent Gd(1) and one C(1) atom to form a mixture of distorted corner and edge-sharing CGd4C trigonal bipyramids. is represented by the CIF card [CIF]
