Gd3Se4 crystallizes in the cubic I-43d space group. Gd(1) is bonded to eight equivalent Se(1) atoms to form a mixture of distorted face, edge, and corner-sharing GdSe8 hexagonal bipyramids. Se(1) is bonded to six equivalent Gd(1) atoms to form a mixture of distorted face, edge, and corner-sharing SeGd6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°.
Gd3Se4 crystallizes in the cubic I-43d space group. Gd(1) is bonded to eight equivalent Se(1) atoms to form a mixture of distorted face, edge, and corner-sharing GdSe8 hexagonal bipyramids. There are four shorter (2.93 Å) and four longer (3.15 Å) Gd(1)-Se(1) bond lengths. Se(1) is bonded to six equivalent Gd(1) atoms to form a mixture of distorted face, edge, and corner-sharing SeGd6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°.
