The structural chemistry of alkali metal thallides shows a broad range of type structures. At an alkali metal : thallium proportion A : Tl 1 : 2 the perceived dependency on the alkali metal involved is conspicuous. Two main structure types are reported with A 15 Tl 27 ( A =K, Rb, Cs) and K 49 Tl 108 . The compound K 49 K 108 with a 3‐dimensional Tl‐substructure has been known since 1993 from Cordier and Müller but so far only with potassium. We here present single crystal X‐Ray structure analyses of the compounds K 49‐y Rb y Tl 108 , and K 49‐y Cs y Tl 108 ( y < 10 ) belonging to the K 49 Tl 108 type structure. Additionally, structures of Rb 49 Tl 109.67 , Cs 3.35 Rb 45.65 Tl 109.71 and Cs 7.49 Rb 41.51 Tl 109.76 are introduced, which prove the possibility of Tl incorporation in the Tl 12 icosahedra in K 49 Tl 108 type structures. The effects of the change in alkali metals on the thallium substructure are discussed as well as the preferred Wyckoff sites of the different alkali metals.
