Abstract

A novel layered phosphate, NH₄Mn₂O(PO₄)(HPO₄) · H₂O, has been synthesized hydrothermally at 220°C under autogeneous water vapor pressure. The compound crystallizes in the orthorhombic space groupP2₁2₁2₁, witha = 6.879(2), b = 7.741(2), andc = 16.244(3)Å. The structure was solved by Patterson and Fourier methods and refined to final agreement factorsR = 0.026, R_w = 0.028. Dominating the structure are zigzag chains of edge-sharing MnO₆ octahedra running parallel toa, which are interconnected via bridging PO₄ groups to form continuous sheets lying in theab plane. Adjacent sheets in thec direction are separated by NH⁺ ₄ ions, and held together via H-bonding. The relationship of the structure to that of the more compact KMn₂O(PO₄)(HPO₄) is discussed.
