Materials Data on TbBi3 by Materials Project

TbBi2Bi crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two bismuth molecules and one TbBi2 sheet oriented in the (0, 0, 1) direction. In the TbBi2 sheet, Tb is bonded in a distorted rectangular see-saw-like geometry to four equivalent Bi atoms. All Tb–Bi bond lengths are 3.06 Å. Bi is bonded in a linear geometry to two equivalent Tb atoms.

二铋化铽（TbBi2）结晶于正交晶系的Cmmm空间群。该结构为二维结构，包含两个铋分子与一片沿(0, 0, 1)方向取向的TbBi2片层。在TbBi2片层中，铽原子以畸变矩形跷跷板型配位几何与四个等价的铋原子成键，所有Tb-Bi键长均为3.06 Å。铋原子以线性配位几何与两个等价的铽原子成键。
