The novel layered oxide BiMo[sub 2]O[sub 7]OH[center dot]2H[sub 2]O was prepared under very mild hydrothermal conditions and the structure determined by ab initio methods from synchrotron X-ray powder diffraction data. The cell is monoclinic, P2[sub 1]/m, Z = 2, with dimensions a = 6.343 21(3) [angstrom], b = 11.597 03(5) [angstrom], c = 5.792 44(3) [angstrom], and [beta] = 113.329(1)[degrees]. Refinement using the Rietveld technique converged with R[sub F[sup 2]] = 5.99%, R[sub P] = 12.67%, R[sub wP] = 16.92%, and x[sup 2] = 5.44 for 34 variables and 453 reflections. The structure is composed of infinite chains of edge-shared molybdenyl dimers which are corner-linked along [010]. These are connected via hexacoordinated bismuth atoms to form sheets parallel to (10[bar 1]) which are loosely held together via a hydrogen-bonding network.
