| Abstract: | Two manganese phosphonates Mn2[{(O3PCH2)2NHR}(H2O)F]·H2O (R = ?C6H11 (1) , ?CH2C5H4N (2) ) have been synthesized by hydrothermal reaction and characterized by single–crystal X–ray diffraction as well as with infrared spectroscopy, elemental analysis and thermogravimetric analysis. The two isomorphous compounds feature layered structures in ab plane, in which the tetramers comprised of two MnO4F2 and two MnO5F polyhedra are cross–linked via phosphonate oxygen atoms to form MnII phosphonate layers. The organic groups of the ligands are orientated toward the interlayer space. |
