摘要制备了无色化合物NaLiS，并用单晶x射线衍射技术对其结构进行了测定。极吸湿NaLiS在P4/nmm （Z = 2）的四方空间群中结晶，胞体参数a = 402.6(1), c = 649.5(2) pm。用微分傅立叶合成方法从720个反反射（216个对称无关反射）中求解该结构。精炼后的最小二乘残差为0.024。抗pbcl型结构的特点是由多层的lis4 /4-四面体在二维空间上的边缘连接和2层穿插的钠组成
Abstract The colourless com pound NaLiS has been prepared and its structure determined by single crystal X-ray diffraction techniques. The very hygroscopic NaLiS crystallizes in the tetragonal space group P4/nmm (Z = 2) with the cell parameters a = 402.6(1), c = 649.5(2) pm. The structure was solved from 720 counter reflections (216 symmetry independent reflections) by differential Fourier syntheses. Refining gives a least squares residue of 0.024. The anti-PbFCl-type structure is characterized by layers of LiS4/4-tetrahedra connected by their edges in two dimensions and 2 interspersed layers of sodium
