Description

Pentacaesium henicosamolybdenum tricosaselenium, Cs5Mo21Se23, Mr=4495.35, hexagonal, P63/m, a=9.6513 (7), c=29.939 (6) A, V=2415.1 (5) A3, Z=2, Dx=6.181 g cm-3, λ(Mo Kα)=0.71073 A, μ=259.9 cm-1, F(000)=3878, T=295 K, R=0.034 for 1290 observed. The main building block of the title compound is the new cluster unit Mo21Se23 whose Mo core consists of six face-linked Mo6 octahedra. These cluster units are linked to each other through Mo-Se interunit bonds and delimit large voids and channels where the Cs ions reside in a tri- or tetra-capped trigonal prismatic Se environment.
