An effective method of synthesis of tin phosphide Sn4P3starting from metallic tin and amorphous red phosphorus by a low-temperature (200°C) solvothermal reaction in ethylenediamine is offered. The key parameters of this process – duration, temperature, and the ratio of initial components (Sn/P) are studied. The structure, phase composition, and morphology of the products are investigated using powder X-ray diffraction and scanning electron microscopy. Different synthetic ways for tin phosphide are discussed and compared with the proposed one. The mechanism of solvothermal preparation of tin phosphide in ethylenediamine is discussed. It is shown that the proposed solvothermal method opens up the possibility of preparing other metal-rich phosphides.
