AB  - The title compound, nonasodium chromium(III) hexakis[molybdate(VI)], 
      beta-Na9CrMo6O24, was prepared by solid-state reactions. This alluaudite-type 
      structure is constituted of infinite layers formed by links between M 2O10 (M = 
      C/Na) dimers and MoO4 tetra-hedra. The Na(+) and Cr(3+) cations are located in 
      the same site with, respectively, 0.25 and 0.75 occupancies. The layers are 
      connected to each other through MoO4 sharing corners, resulting an in open 
      three-dimensional framework with hexa-gonal-form cavities occupied by Na(+) 
      cations. The proposed structural model is supported by charge-distribution 
      (CHARDI) and bond-valence-sum (BVS) analysis. All atoms are on general positions 
      except for one Mo, two Na (site symmetry 2) and another Na site (site symmetry 
      -1). A comparison is made with the similar structures Na4Co(MoO4)3, Na2Ni(MoO4)2, 
      Cu1.35Fe3(PO4)3 and NaAgFeMn2(PO4)3.
