The compound described by Yb(SbSe2)2 crystallizes in the orthorhombic Pnma space group. Yb(1) is bonded in a 7-coordinate geometry to two equivalent Se(1), two equivalent Se(2), two equivalent Se(3), and two equivalent Se(4) atoms. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to one Se(2), two equivalent Se(4), and three equivalent Se(1) atoms to form a mixture of edge and corner-sharing SbSe6 octahedra. The corner-sharing octahedral tilt angles range from 47-70°. In the second Sb site, Sb(2) is bonded to one Se(4), two equivalent Se(2), and three equivalent Se(3) atoms to form a mixture of edge and corner-sharing SbSe6 octahedra. The corner-sharing octahedral tilt angles range from 47-70°. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded to two equivalent Yb(1) and three equivalent Sb(1) atoms to form a mixture of edge and corner-sharing SeYb2Sb3 square pyramids. In the second Se site, Se(2) is bonded to two equivalent Yb(1), one Sb(1), and two equivalent Sb(2) atoms to form a mixture of distorted edge and corner-sharing SeYb2Sb3 trigonal bipyramids. In the third Se site, Se(3) is bonded to two equivalent Yb(1) and three equivalent Sb(2) atoms to form a mixture of distorted edge and corner-sharing SeYb2Sb3 trigonal bipyramids. In the fourth Se site, Se(4) is bonded in a 5-coordinate geometry to two equivalent Yb(1), one Sb(2), and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
