The crystal structure of synthetic manganese sodium borophosphate hydrate Na(H2O)[Mn(H2O)(2)(BP2O8)] was refined based on X-ray diffraction data. The compound was prepared by soft hydrothermal synthesis in the MnCl2-Na3PO4-B2O3-H2O system. The unit-cell parameters are a= 9.602(1) A..., c= 16.037(3) A..., sp. gr. P6(5)22, Z= 6, D (x) = 2.57 g/cm(3). The water molecules were found to be statistically distributed in the channels of the mixed anionic paraframework consisting of (BO4) and (PO4) tetrahedra and [MnO4(H2O)(2)] octahedra. The hydrogen atoms of the water molecules coordinated to the Mn2 cations were located and their positional and thermal parameters were refined. The crystal-chemical features of borophosphates of the general formula A (x) M(H2O)(2)(BP2O8)(H2O) are considered.
