Abstract

TmCu2Ge2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Tm is bonded in a 8-coordinate geometry to eight equivalent Cu and eight equivalent Ge atoms. All Tm–Cu bond lengths are 3.14 Å. All Tm–Ge bond lengths are 3.26 Å. Cu is bonded in a 9-coordinate geometry to four equivalent Tm, one Cu, and four equivalent Ge atoms. The Cu–Cu bond length is 2.33 Å. All Cu–Ge bond lengths are 2.47 Å. Ge is bonded in a 4-coordinate geometry to four equivalent Tm and four equivalent Cu atoms.
