通过加入模板剂哌嗪以及辅助配体 1,10-菲啰啉, 在水热条件下合成得到了两个金属有机膦酸化合物Mn3(4-piH)2(H2O)3?H2O (1) 和 Mn5(4-piH)2(4-piH2)2(phen)2(H2O)4 (2) (4-piH4 为 4-膦酸间苯二甲酸). 两者都显示层状结构. 在化合物1中, 由三角形的{Mn3O3}三聚体通过共边或共角组成{Mn3O3}O2复杂柱型链, 链与链之间由{PO3C}连接形成无机层, 苯基以及未配位的羧基悬挂在无机层的两侧. 在化合物 2 中, 由{Mn1O6}和{Mn3O4N2}八面体共边形成{Mn4O6}四核簇, 四核簇之间通过{Mn2O6}八面体共角连接形成一维之字形无机链, 相邻链间由 4-pi4?配体连接形成无机有机杂化的二维层状结构. 磁性研究表明两个化合物中锰离子之间均存在反铁磁相互作用, 在低温下化合物 1 表现出变磁体的行为.
Two organometallic phosphonic compounds Mn3 (4-piH) 2 (H2O) 3? H2O (1) were synthesized by adding the template piperazine and the auxiliary ligand 1,10-phenanthroline under hydrothermal conditions Mn5 (4-piH) 2 (4-piH2) 2 (phen) 2 (H2O) 4 (2) (4-piH4 is 4-phosphonic isophthalic acid.) Both showed a lamellar structure. , The triangular {Mn3O3} trimer is formed by the co-edge or common angle to form a complex Mn3O3} O2 column, the inorganic layer is formed by the {PO3C} linkage between the chain and the phenyl group, and the uncoordinated carboxyl group is suspended On both sides of the inorganic layer, in the compound 2, the {Mn4O6} tetranuclear cluster was formed by the co-edge of {Mn1O6} and {Mn3O4N2} octahedra and the tetranuclear clusters were connected by the {Mn2O6} octahedral angle to form a one-dimensional Shaped inorganic chain, the adjacent chains formed by the 4-pi4? Ligands to form a two-dimensional inorganic-organic layered structure.Microscopic studies have shown that there is antiferromagnetic interaction between the two compounds manganese ions at low temperatures Compound 1 shows the behavior of a magnet.
