Crystal data on some potassium lithium metal sulphides (KLiMS₂, M being Zn, Mn or Fe)

Compounds of the formula KLiMS₂, where M is one of the divalent transition elements Zn, Mn or Fe, belong to the tetragonal crystal system. They are not, however, isomorphous. KLiZnS₂: P, a = 6.600(5), c = 15.570(5) Å; KLiMnS₂: P, a = 6.800(5), c = 11.055(5) Å; KLiFeS₂: I, a = 3.840(5), c = 13.270(5) Å. X-ray powder diffraction data for all three compounds are given. The JCPDS Diffraction File Nos. for these compounds are: KLiZnS₂ 33-1494; KLiMnS₂ 33-1493; KLiFeS₂ 33-1492.
