Abstract: The title compound, trineodymium silicotetramolybdate, is isotypic with La3Mo4SiO14. The crystal structure contains ribbons made of chains of triangular Mo3O13 units and chains of edge-sharing MoO6 octahedra. The ribbons are separated from each other by the Nd3+ and Si4+ cations. The three distinct Nd3+ cations are surrounded by eight to ten O atoms, and the Si4+ is tetrahedrally coordinated. Except for two Mo and four O sites, all other sites (three Nd, one Mo, one Si and six O) are located on mirror planes.
