Özet:
The synthesis of new manganese phosphate compound, Sr2MnP3O11, by hydrothermal reaction of Mn2O3, SrCO3 and H3PO4 in presence of water at 230 for 5 days is reported. The compound crystallizes in the space group P 21/c of the monoclinic system with three formula units in a cell of dimensions a.6.6410(13) b.6.8341(14) c.19.055(14) .99.22(3) V.853.6(3) The structure is composed of MnO6, PO4 and P2O7 groups and Sr cations. It has three dimensional structure including channels n which the Sr cations are placed.The pale pink single crystals of the Hureaulite mineral, Mn5(H2O)4[PO3(OH)]2[PO4]2, were synthesized hydrothermally via the reaction of SrCO3, MnCl2, H3PO4 and H2O at 180C for 3 days. The compound is in the crystal system of monoclinic with unitcell parameters a.17.600(4), b.9.1214(18), c.9.4786(19) and .96.52(3)and in the space group C2/c. The structure possesses a three-dimensional architecture containing channels and is made up of MnO6 and PO4, which are joined with others by sharing corners.All detailed structural information of the synthesized materials was done via commercial software programs SHELX and Crystal Structure.
