| 摘要: 本文报道了1个新的有机膦酸锰簇合物[Mn5O3(C11H9PO3)2(PhCOO)5(phen)2]·2H2O (1)的合成、结构及磁性质。单晶结构分析显示化合物1含有[Mn5O3]9+核结构，该结构通过连接5个金属离子形成了篮子型簇结构。化合物1的直流磁化率测试表明金属离子之间存在反铁磁相互作用。交流磁化率测试没有发现实部和虚部出现频率依赖行为，说明化合物1不是一个单分子磁体。 |

| Abstract: This paper reports the synthesis, crystal structure and magnetic properties of a new manganese phosphonate [Mn5O3(C11H9PO3)2(PhCOO)5(phen)2]·2H2O(1) based on naphthalene-1-ylmethylphosphonic acid (C11H9PO3H2). Single-crystal X-ray analysis reveals that compound 1 contains [Mn5O3]9+ cores with five metal sites arranged in a basket-like cluster structure. Solid-state dc magnetic susceptibilities measurement of compound 1 reveals that dominant antiferromagnetic interactions are propagated between the magnetic centers. The ac magnetic measurement on compound 1 reveals that both the in-phase and the out-phase signals are frequency independent, which indicates that compound 1 is not a single-molecule-magnet (SMM).
