摘要
利用配体4-[三-(羟甲基)甲基]吡啶(4-thmpyH3),成功合成了 3种新型金属有机骨架[Mn4ⅡMn8ⅡO2(4-thmpy)4(O2CPh)10(OMe)2(H2O)2](1),[Mn4ⅡCo6ⅡO(4-thmpy)4(O2CPh)6(H2O)4](2)和[Mn4ⅡNi6ⅡO(4-thmpy)4(O2CPh)6(H2O)4](3).晶体结构分析表明,化合物1表现为圆盘状十二核[Mn4ⅢMn8Ⅱ]零维簇.化合物2和3是同构的.化合物2中的十核簇[Mn4ⅡCo6Ⅱ]节点可以看作是4个共界立方烷[MnⅡCo3ⅡO4]组成的超四面体,每个十核簇[Mn4ⅡCo6Ⅱ]通过6个4-thmpy3-与相邻的6个十核簇[Mn4ⅡCo6Ⅱ]连接,形成NaCl型三维拓扑结构.磁性研究表明,化合物1-3金属离子之间存在反铁磁相互作用.
Abstract
Three new metal organic frameworks,[Mn4ⅡMn8ⅡO2(4-thmpy)4(O2CPh)10(OMe)2(H2O)2]·3CH3OH·4H2O(1),[Mn4ⅡCo6ⅡO(4-thmpy)4(O2CPh)6(H2O)4]·CH3OH·3H2O(2),and[Mn4ⅡNi6ⅡO(4-thmpy)4(O2CPh)6(H2O)4]·2CH3 OH·2H2O(3),have been successfully synthesized by using 4-[tri-(hydroxymethyl)methyl]pyridine(4-thmpyH3)as ligand.Crystal structure analyses show that com-pound 1 is a disk-like twelve nuclear[Mn4ⅡMn8Ⅱ]OD cluster.Compounds 2 and 3 are isomorphic,and the decanuclear heteronuclear cluster[Mn4ⅡCo6Ⅱ]node in compound 2 can be seen as a hyper-tetrahedron of four coboundary cubic alkanes[MnⅡCo3ⅡO4],then each ten-nuclear heteronuclear cluster[Mn4ⅡCo6Ⅱ]is connected by six 4-thmpy3-with six adjacent decanuclear clusters[Mn4ⅡCoⅡ],forming the NaCl-type 3D topological structure.Magnetic studies showed that there exist antiferromagnetic interactions between metal ions in 1-3.
