Redetermination of Mn_1.44Mo₈O₁₁: evidence of pairwise distortion of octahedral molybdenum chains

P. Gall and P. Gougeon

Abstract: Redetermination of the structure of manganese octamolybdenum undecaoxide, Mn_1.44Mo₈O₁₁, revealed a doubling of the unit cell. The structure consists of infinite chains of trans-edge-sharing Mo₆ octahedra cross-linked through O atoms to delimit tunnels in which the disordered Mn²⁺ cations reside. In comparison with the previous refinement [Carlson et al. (1989). J. Less Common Met. 156, 325-339], the metallic chains exhibit a pairwise distortion, as expected from theoretical calculations.
