Description
Caesium molybdenum selenide, Cs3Mo15Se17, Mr=3180.14, hexagonal, P63/m, a=9.624(2), c=20.898(8) A, V=1676.4(7) A3, Z=2, Dx=6.276 g cm-3, λ(Mo Kα)=0.71073 A, μ=266.5 cm-1, F(000)=2746, T=293 K, R=0.028 for 1028 reflections with I≥2σ(I) and 58 parameters. The title compound is isostructural with Rb3Mo15Se17 and thus its structure contains as the main building block the Mo15Se17 cluster unit whose Mo core is built up by four face-sharing Mo6 octahedra. Whereas the intracluster Mo-Mo distances as well as the Mo-Se ones are identical to within ±0.01 A in both compounds, owing to the same cationic charge transfer towards the Mo15S17 unit, a slight lengthening of the intercluster Mo-Mo distance from 3.268 to 3.318 A is observed, as expected, when the size of the cation increases.
