Materials Data on SnSe by Materials Project

SnSe crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two SnSe sheets oriented in the (0, 1, 0) direction. Sn2+ is bonded in a rectangular see-saw-like geometry to four equivalent Se2- atoms. There are two shorter (2.76 Å) and two longer (3.06 Å) Sn–Se bond lengths. Se2- is bonded in a rectangular see-saw-like geometry to four equivalent Sn2+ atoms.

硒化锡（SnSe）结晶于正交晶系Cmcm空间群。该晶体结构为二维结构，包含两片沿(0, 1, 0)晶向取向的SnSe片层。Sn²⁺以矩形跷跷板型配位几何与四个等价的Se²⁻原子成键，Sn-Se键存在两组键长，分别为较短的2.76 Å与较长的3.06 Å。Se²⁻同样以矩形跷跷板型配位几何与四个等价的Sn²⁺原子成键。
