The material described by YbBi2Te4 crystallizes in the tetragonal I-42d space group. Yb(1) is bonded in a 8-coordinate geometry to eight equivalent Te(1) atoms. Bi(1) is bonded to six equivalent Te(1) atoms to form edge-sharing BiTe6 octahedra. Te(1) is bonded to two equivalent Yb(1) and three equivalent Bi(1) atoms to form a mixture of distorted face, corner, and edge-sharing TeYb2Bi3 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
