| 摘要: 以（NH4）6[MnMo9O32]·8H2O为前体原料，与CuCl2及吡啶反应得到了2个Waugh型钼酸盐[Cu（H2O）4]3MnMo9O32·6H2O（1）和[Cu（H2O）4][Cu（C5H5N）（H2O）2]2（C5H5N）MnMo9O32·4H2O（2），并用元素分析、X-射线单晶衍射、红外光谱、固体紫外可见光谱、近红外光谱和热重分析对其进行了表征，并研究了化合物1的磁性质。晶体结构表明，化合物1属于三方晶系，空间群为R32；化合物2属于单斜晶系，空间群为C2/c。化合物1中Cu2+与[MnMo9O32]6-连接形成了三维二重穿插的α-Po拓扑结构。化合物2中单核铜“Cu（H2O）4”和双核铜建筑块“[Cu2（C5H5N）2（H2O）4]”作为桥连接阴离子[MnMo9O32]6-形成了三维网络结构。其中化合物2是首例有机配体参与过渡金属离子配位的Waugh型化合物。 |

| Abstract: Two Waugh molybdates based on [MnMo9O32]6-: [Cu(H2O)4]3MnMo9O32·6H2O (1) and [Cu(H2O)4][Cu(C5H5N)(H2O)2]2(C5H5N)MnMo9O32·4H2O (2) have been isolated by reacting of (NH4)6MnMo9O32·6H2O, CuCl2 and pyridine in aqueous solution, and characterized by elemental analysis, single-crystal X-ray diffraction, IR, NIRand TG. The magnetic properties of compound 1 have also been studied. Crystal structural analyses indicate that the compound 1 crystallizes in the triclinic crystal system and space group R32, and compound 2 crystallizes in the monoclinic crystal system and space group C2/c. In compound 1, the polyoxoanions [MnMo9O32]6- are linked by Cu2+ ions to form a 3D framework with α-Po topology. In compound 2, the polyoxoanions [MnMo9O32]6- are linked by the "Cu(H2O)4" and "[Cu2(C5H5N)2(H2O)4]" groups to form a 3Dnetwork. It is noteworthy that compound 2 is the first example of Waugh-type compound, in which organic ligands coordinate to transition metal ions. CCDC: 999721, 1; 999720, 2. |
