Spectroscopic and magnetic studies on α-Li 3 Fe 2 (PO 4 ) 3 show an interesting behavior below the transition temperature (29 K). The compound orders antiferromagnetically, presenting a weak ferromagnetic moment, which diminishes with temperature. In the same region of temperatures, the Mssbauer...
采用水热合成方法得到一例新的过渡金属铁(Fe)的含肼硫酸盐:[Fe(N 2H 5)2(SO 4)2]n (1).用单晶X 射线衍射的方法对其晶体结构进行了表征.结果表明,该化合物以硫酸根为桥连配体,质子化的肼分子为端基配体,形成一维(1D)链状结构.肼分子和硫酸根形成的链间氢键,将1D 链进一步扩展成三维(3D)结构.磁性测试...
The complex mechanism of pressure-induced transformation of β-Fe2O3, involving also the formation of Rh2O3-II-type Fe2O3 and post-perovskite-Fe2O3 structure, is suggested and discussed with respect to a bimodal size distribution of precursor nanoparticles. Iron(III) oxide is a polymorphic ...
Obviously, the interfaces among the heterojunctions will be greatly FeCl3 ⋅ 6H2O → Fe3+ + 3Cl− (1) N H 4VO3 → N H + 4 + VO3− (2) Fe3+ + VO3− → FeVO4 (3) H2O → H + + OH− (4) Fe3+ + 3OH− → Fe (OH)3 (5) FeVO4 + VO3− + N H + ...
At the corners of the octahedron, for the longest Fe-O bond, there is an associated OH group (O(3)–H1O3 bond), for the medium Fe-O bond, there is an associated H2O water molecule (O(5)–H1O5 and O(5)–H2O5 bonds), while, for the shortest Fe-O bond, there are no H ...
