Hexapotassium Hexaselenodistannate(III) K 6 Sn 2 Se 6 – Synthesis, Structure, and Properties of a New Salt‐like Sn III Compound Reaction of stoichiometric amounts of potassium, tin, and selenium in sealed silica tubes yield at 900 °C K 6 Sn 2 Se 6 ( 1 ) as red‐orange solid of which small particles are very suitable for X‐ray structural analysis. Space group P 2 1 / c , lattice dimensions at 203 K: a = 905.6(2), b = 1277.4(3), c = 888.7(2) pm, β = 115.86(3)°, R 1 = 0.0332. Besides Cs 6 Sn 2 Se 6 , 1 represents the second hexaselenostannate(III) to be known and structurally characterized. Thus, it contributes to the completion of the hexachalcogenostannate(III) family. Additionally, 1 is isostructural and in some cases even isotypic to homologue compounds of the elements silicon and germanium.
