Abstract
We have redetermined the structure of LaMo 5 O 8 by single-crystal X-ray diffraction. Its structure has been determined previously by powder X-ray and neutron diffraction with rather high R factors resulting from impurities in the sample. The crystal structure of LaMo 5 O 8 is based on Mo 10 O 18 cluster units, the Mo cores of which are Mo 10 bioctahedra resulting from the edge-sharing of two Mo 6 octahedra. These bioctahedral Mo 10 O 18 cluster units share opposite O atoms to form infinite molybdenum oxide chains in which the Mo 10 clusters are strongly linked through short Mo-Mo intercluster bonds of 2.6890 (7) A and two weaker Mo-Mo bonds of 2.9108 (5) and 3.0911 (5) A
