Abstract
The structure of the fibrillar ammonium trimolybdate monohydrate (NH4) (2)Mo3O10 . H2O was solved by the Direct Method and Powder Diffraction package POWSIM, and refined by the Rietveld method to R(F) = 6.4 and R(wp) = 17.1%. Distorted edge-shared MoO6 octahedra (Mo-O = 1.71-2.62) form infinite chains, built up of Mo3O10 units, parallel to the [010] axis. The space group is P2(1)/m (11), with lattice parameters a = 9. 638(1), b = 7.577(2), c = 8.537(1) Angstrom, beta = 112.89(1)degrees, V = 574.4(2) Angstrom(3), Z = 2. (C) 1995 Academic Press, Inc.
