Single crystals of dicaesium trimolybdate have been grown by solid-state re
action. The structure is built up of infinite molybdate chains interleaved
by Cs atoms. The Mo atoms exhibit two coordination modes towards O atoms, n
amely, CN6 and CN5 as distorted octahedral and trigonal bipyramidal polyhed
ra, respectively, while Cs atoms, responsible for the cohesion of the netwo
rk, sit in bicapped dodecahedra.
