The ultrafine Mn{sub 2}SnO{sub 4} nanoparticles with diameters of 5-10 nm have been prepared by thermal decomposition of precursor MnSn(OH){sub 6}. The MnSn(OH){sub 6} nanoparticles precursor was synthesized by a hydrothermal microemulsion method. X-ray diffraction, transmission electron microscopy, high-resolution transmission electron microscopy and electron diffraction have been employed to characterize the crystal structures and morphologies of the as-prepared samples. High-resolution transmission electron microscopy observations revealed that the as-synthesized nanoparticles were single crystals. The thermal characterization was studied by differential thermal analysis and thermogravimetry analysis measurements. Electrochemical test showed that the Mn{sub 2}SnO{sub 4} nanoparticles exhibited a high initial charge-discharge capacity of 1320 mAh/g.
