The hydrothermal reaction of Na2MoO4?2H_2O, SmCl3 in acidified H_2O/CH3CN solution gives rise to the title compound as colorless needle crystals, which was characterized by elemental analysis, IR and X-ray single-crystal diffraction techniques. Crystallographic data: Orthorhombic, Pnma, H3Mo3NaO11, Mr = 489.83, a = 8.411(2), b = 7.566(2), c = 14.359(3) ?, V = 913.8(3) ? 3, Z = 4, Dc = 3.560 g·cm-3, ( = 4.148 mm-1, F(000) = 912, the final R = 0.0649 and wR = 0.1569 for 1885 observed reflections with I ≥ 2σ(I). The title compound consists of infinite chains built up by distorted {MoO6} octahedra via edge sharing, which are further connected into a three-dimensional framework by sodium ions and protoned water molecules.
