The crystal structure described by Gd2ReC2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent C(1) and two equivalent C(2) atoms. In the second Gd site, Gd(2) is bonded to two equivalent C(1) and three equivalent C(2) atoms to form a mixture of edge and corner-sharing GdC5 square pyramids. Re(1) is bonded in a distorted trigonal planar geometry to one C(2) and two equivalent C(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded to two equivalent Gd(1), two equivalent Gd(2), and two equivalent Re(1) atoms to form CGd4Re2 octahedra that share corners with two equivalent C(1)Gd4Re2 octahedra, corners with two equivalent C(2)Gd5Re octahedra, edges with two equivalent C(1)Gd4Re2 octahedra, and edges with five equivalent C(2)Gd5Re octahedra. The corner-sharing octahedral tilt angles range from 12-41°. In the second C site, C(2) is bonded to two equivalent Gd(1), three equivalent Gd(2), and one Re(1) atom to form CGd5Re octahedra that share corners with two equivalent C(1)Gd4Re2 octahedra, corners with four equivalent C(2)Gd5Re octahedra, edges with two equivalent C(2)Gd5Re octahedra, and edges with five equivalent C(1)Gd4Re2 octahedra. The corner-sharing octahedral tilt angles range from 5-41°. is represented by the Crystallographic Information File (CIF) [CIF]
