Materials Data on TbSiNi by Materials Project
TbNiSi crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb3+ is bonded in a 6-coordinate geometry to six equivalent Si4- atoms. There are a spread of Tb–Si bond distances ranging from 2.96–3.15 Å. Ni1+ is bonded to four equivalent Si4- atoms to form a mixture of corner and edge-sharing NiSi4 tetrahedra. There are a spread of Ni–Si bond distances ranging from 2.45–2.56 Å. Si4- is bonded in a 10-coordinate geometry to six equivalent Tb3+ and four equivalent Ni1+ atoms.
