The crystal structure of polycrystalline fibrillar sodium trimolybdate Na 2 Mo 3 O 10 . 3 H 2 O, has been solved ab initio by Powder Diffraction – Direct Methods package POWSIM. The structure was refined by the Rietveld method with final discrepancy factors R F = 6.9 and R wp = 17.1%. The structure consists of polymeric chains of Mo‐O polyhedra parallel to the b axis. The space group is C2/m (12), a = 17.179(1), b = 3.7757(3), c = 10.8571(8) Å, β = 115.417(6)°, V = 636.06(6) Å 3 , Z = 2.
