Abstract
Pentacaesium henicosamolybdenum tricosasulfur is isostructural with Cs 5Mo21Se23 and is the third member in the series M2n-1Mo6n+3X6n+5 (M = Rb, Ca; X = S, Se, Te). Its crystal structure contains as the main bui lding block an Mo21S23 cluster unit, the Mo core of which consists of six face-sharing Mo-6 octahedra. The decrease in the ionic radius of t he chalcogen results in a shortening of the Mo-Mo intertriangle distan ces while the intratriangle ones do not change significantly. The shor test intercluster Mo-Mo distance also decreases from 3.342(3) Angstrom in Cs5Mo21Se23 to 3.1687(9) Angstrom in Cs5Mo21S23.
