Six Mo(IV)-Cu(II) complexes, Cu(tpa)[Mo(CN)(8)]·15H(2)O (1, tpa = tris(2-pyridylmethyl)amine), Cu(tren)[Mo(CN)(8)]·5.25H(2)O (2, tren = tris(2-aminoethyl)amine), [Cu(en)(2)][Cu(0.5)(en)][Cu(0.5)(en)(H(2)O)][Mo(CN)(8)]·4H(2)O (3, en = ethylenediamine), Cu(bapa)Mo(CN)(8)·12.5H(2)O (4, bapa = bis(3-aminopropyl)amine), Cu(bapen)[Mo(CN)(8)]·4H(2)O (5, bapen = N,N'-bis(3-aminopropyl)ethylenediamine), and [Cu(pn)(2)][Cu(pn)][Mo(CN)(8)]·3.5H(2)O (6, pn = 1,3-diaminopropane), were synthesized and characterized. Single-crystal X-ray diffraction analyses show that 1-6 have different structures varying from trinuclear clusters (1-2), a one-dimensional belt (3), two-dimensional grids (4-5), to a three-dimensional structure (6). Magnetic and ESR measurements suggest that 1-6 exhibit thermally reversible photoresponsive properties on UV light irradiation through a Mo(IV)-to-Cu(II) charge transfer mechanism. A trinuclear compound Cu(II)(tpa)Mo(V)(CN)(8) (7) was synthesized as a model of the photoinduced intermediate.
六个 Mo(IV)-Cu(II) 配合物，Cu(tpa)[Mo(CN)(8)]·15H(2)O (1, tpa = tris(2-吡啶基甲基)胺)、Cu(tren)[Mo(CN)(8)]·5.25H(2)O (2, tren = tris(2-氨基乙基)胺)、[Cu(en)(2)][Cu(0.5)(en)][Cu(0.5)(en)(H(2)O)][Mo(CN)(8)]·4H(2)O (3, en = 乙二胺)、Cu(bapa)Mo(CN)(8)·12.5H(2)O (4, bapa = bis(3-氨基丙基)胺)、Cu(bapen)[Mo(CN)(8)]·4H(2)O (5, bapen = N,N'-双(3-氨基丙基)乙二胺)和[Cu(pn)(2)][Cu(pn)][Mo(CN)(8)]·3.5H(2)O (6, pn = 1,3-二氨基丙烷)被合成并进行了表征。单晶 X 射线衍射分析表明，1-6 的结构不同，从三核簇（1-2）、一维带（3）、二维网格（4-5）到三维结构（6）。磁学和 ESR 测量表明，1-6 通过 Mo(IV)-到-Cu(II) 电荷转移机制在紫外线照射下表现出热可逆光响应特性。合成了一个三核化合物Cu(II)(tpa)Mo(V)(CN)(8) (7)作为光诱导中间物的模型。
