Li(RhSi)2 crystallizes in the tetragonal P4/mbm space group. Li(1) is bonded in a 14-coordinate geometry to two equivalent Li(1), eight equivalent Rh(1), and four equivalent Si(1) atoms. Rh(1) is bonded in a 6-coordinate geometry to four equivalent Li(1) and six equivalent Si(1) atoms. Si(1) is bonded in a 8-coordinate geometry to two equivalent Li(1) and six equivalent Rh(1) atoms.
Li(RhSi)2 crystallizes in the tetragonal P4/mbm space group. Li(1) is bonded in a 14-coordinate geometry to two equivalent Li(1), eight equivalent Rh(1), and four equivalent Si(1) atoms. Both Li(1)-Li(1) bond lengths are 2.74 Å. All Li(1)-Rh(1) bond lengths are 2.99 Å. All Li(1)-Si(1) bond lengths are 2.68 Å. Rh(1) is bonded in a 6-coordinate geometry to four equivalent Li(1) and six equivalent Si(1) atoms. There are two shorter (2.45 Å) and four longer (2.48 Å) Rh(1)-Si(1) bond lengths. Si(1) is bonded in a 8-coordinate geometry to two equivalent Li(1) and six equivalent Rh(1) atoms.
