Materials Data on Na(SmTe2)3 by Materials Project

SmNa(SmTe2)2(Te)2 crystallizes in the orthorhombic Cmmm space group. The structure is two-dimensional and consists of two samarium molecules; four tellurium molecules; and one Na(SmTe2)2 sheet oriented in the (0, 0, 1) direction. In the Na(SmTe2)2 sheet, Na1+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent Te+1.67- atoms. All Na–Te bond lengths are 3.12 Å. Sm3+ is bonded in a linear geometry to two equivalent Te+1.67- atoms. Both Sm–Te bond lengths are 2.84 Å. Te+1.67- is bonded in a linear geometry to one Na1+ and one Sm3+ atom.

SmNa(SmTe₂)₂(Te)₂结晶于斜方晶系（orthorhombic）的Cmmm空间群。该结构为二维结构，包含两个钐分子、四个碲分子，以及一片沿(0, 0, 1)方向取向的Na(SmTe₂)₂片层。在Na(SmTe₂)₂片层中，Na⁺以畸变矩形跷跷板状配位几何与四个等价的Te⁺1.67⁻原子成键，所有Na–Te键长均为3.12 Å。Sm³⁺以直线型配位几何与两个等价的Te⁺1.67⁻原子成键，两条Sm–Te键长均为2.84 Å。Te⁺1.67⁻以直线型配位几何分别与一个Na⁺和一个Sm³⁺原子成键。
