Neodymium hepta molybdate crystals grown from silica gels [1] are characterized employing energy dispersine X-ray analysis, X-ray and electron diffraction, infra-red spectroscopy, optical microscopy and scanning electron microscopy techniques and the results obtained are presented. The crystals are established to have the composition Nd(2)Mo(7)O(24)27H(2)O. The results of electron diffraction studies indicate the material to be thermally unstable. The crystals growing within the gel medium exhibit varied morphologies including square and octagonal platelets, cuboids, multifaceted crystals, coalesced and aggregated forms and spherulites. The spherulitic morphology is shown to arise due to crystallites adhering in a spherical envelope and are not as a result of crystal fibres radiating out from a centrally located common nucleus. The morphology of the building blocks of the crust at the gel reactant interface is discussed.
