Gd2CF2 crystallizes in the trigonal P-3m1 space group. Gd(1) is bonded to three equivalent C(1) and four equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing GdC3F4 pentagonal bipyramids. C(1) is bonded to six equivalent Gd(1) atoms to form CGd6 octahedra that share corners with twelve equivalent F(1)Gd4 tetrahedra, edges with six equivalent C(1)Gd6 octahedra, and edges with six equivalent F(1)Gd4 tetrahedra. F(1) is bonded to four equivalent Gd(1) atoms to form distorted FGd4 tetrahedra that share corners with six equivalent C(1)Gd6 octahedra, corners with six equivalent F(1)Gd4 tetrahedra, edges with three equivalent C(1)Gd6 octahedra, and edges with three equivalent F(1)Gd4 tetrahedra. The corner-sharing octahedral tilt angles range from 5-57°.
Gd2CF2 crystallizes in the trigonal P-3m1 space group. Gd(1) is bonded to three equivalent C(1) and four equivalent F(1) atoms to form a mixture of distorted edge and corner-sharing GdC3F4 pentagonal bipyramids. All Gd(1)-C(1) bond lengths are 2.55 Å. There are three shorter (2.42 Å) and one longer (2.56 Å) Gd(1)-F(1) bond length. C(1) is bonded to six equivalent Gd(1) atoms to form CGd6 octahedra that share corners with twelve equivalent F(1)Gd4 tetrahedra, edges with six equivalent C(1)Gd6 octahedra, and edges with six equivalent F(1)Gd4 tetrahedra.
