Synthesis and Characterization of a New Open-framework Iron Phosphate
摘要
Abstract
Synthesis of novel iron phosphates has gained much attention due to their structure diversity and unique magnetic property. In this work, a new iron phosphate JU94( 2H3O [Fe2P2O8(OH)2]) with novel three-dimensional open framework has been hydrothermally synthesized using dipropylenetriamine as the structure-directing agent( SDA) . Its structure was determined by single-crystal X-ray diffraction. It crystallizes in monoclinics pace group, P21/c, with a=0.97566(5) nm, b=0.98560(5) nm, c=1.24514(5) nm,β=129.651(3)o, V=0.92189(8) nm3. The framework structure is made of tetranuclear iron-oxygen clusters as building unit formed by connection of FeO6 and PO4 polyhedra, which contains intersecting 8-ring channels along the [101], [101], [010] and [111] directions. Water molecules are occluded in the free space of channels. M?ssbauer analysis shows that there are two types of Fe atoms in the framework, and they are both trivalent. Magnetic measurement shows anti-ferromagnetic ordering of JU94 at room temperature.关键词
