A series of borate-rich metalloborophosphates Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mg, Mn, Fe, Co, Ni, Cu, Zn): Synthesis, structure and magnetic susceptibility
چکیده انگلیسی

A series of metalloborophosphates Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mg, Mn, Fe, Co, Ni, Cu, Zn) have been prepared hydrothermally and their structures have been solved by single-crystal diffraction techniques. They all crystallize in a hexagonal space group P63 and form a 3D microporous structure with 12-membered ring channels consisted of octahedral (MIIO6), tetrahedral (BO4, PO4) and triangular (BO2(OH)) units, in which the counter Na+ cations and water molecules are located. The Na+ cations are mobile and can be exchanged by Li+ in a melt of LiNO3. Their open frameworks are thermal stable up to about 500 °C. Completed solid solutions between two different transition metals can also be obtained. Magnetic properties of Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mn, Co, Ni, Cu) have been investigated.

A series of metalloborophosphates Na2[MIIB3P2O11(OH)]·0.67H2O (MII=Mg, Mn, Fe, Co, Ni, Cu, Zn) were synthesized under hydrothermal conditions (473 K). The structure consists of microporous 3D open framework with 12-membered ring channels composed of octahedral (MIIO6), tetrahedral (BO4, PO4) and triangular (BO2(OH)) units.Figure optionsDownload as PowerPoint slide
