| 英文摘要 | Two new compounds, Sr6Sb4Co3O14(OH)(10) (SSC) and Sr6Sb4Mn3O14(OH)(10) (SSM), were synthesized under hydrothermal conditions in an alkaline medium. Their structures were determined by powder X. ray diffraction using Rietveld analysis, and the topology of the metal cation network was discussed. These two isostructural compounds crystallize in a garnet. related or hydrogarnet. related structure with the space group (l) over bar 43d and the lattice parameters (a) are 1.30634(2) nm(SSC) and 1.31367(1) nm(SSM). The SbO6 octahedron and MO4 (M=Co, Mn) tetrahedron share corners with each other to form the backbone of the structure. The topology of the Sb5+ and M2+ (M= Co, Mn) network is ctn, which is the C3N4 network. The Sb5+ node is three. connected and that of M2+ (M= Co, Mn) is four. connected. The distribution of the M2+ (M= Co, Mn) cations in the structure is in a fanlike mode with a thp topology, i.e., a network of Th atoms in Th3P4. These two compounds are antiferromagnetic. Sr6Sb4Co3O14(OH)(10) exhibits a net magnetic moment, which may be related to the canting ordering of Co2+ ions below 10 K. Sr6Sb4Co3O14(OH)(10) and Sr6Sb4Mn3O14(OH)(10) decompose above 300 degrees C and give rise to the perovskite. type compounds Sr-2(Sb, M)(2)O-6(M=Co, Mn) as the main phases in the products after treatment at 900 degrees C under atmospheric conditions. |
