P. Gougeon, P. Gall and W. H. McCarroll

Abstract: Strontium lanthanum pentamolybdenum octaoxide, Sr_0.44La_0.56Mo₅O₈, belongs to the AMo₅O₈ structure type (A = Ca, Sr, Sn, Pb, Eu, La to Gd). Its crystal structure consists of bioctahedral Mo₁₀O₁₈ cluster units interconnected through Mo-Mo bonds of 2.7322 (7) Å to form infinite molybdenum oxide chains. These are linked by corner O atoms to create four-sided channels along [100], in which the La³⁺ and Sr²⁺ cations are statistically distributed over one unique position.
