Materials Data on Tb(CuS)2 by Materials Project
Tb(CuS)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Tb is bonded to six equivalent Cu and six equivalent S atoms to form distorted face-sharing TbCu6S6 cuboctahedra. All Tb–Cu bond lengths are 3.10 Å. All Tb–S bond lengths are 2.86 Å. Cu is bonded in a 4-coordinate geometry to three equivalent Tb and four equivalent S atoms. There are three shorter (2.31 Å) and one longer (2.55 Å) Cu–S bond lengths. S is bonded in a 7-coordinate geometry to three equivalent Tb and four equivalent Cu atoms.
