  Three hydrazone type ligands, namely 2-H, 3, and 4, which were designed to form 1:1 complexes with lanthanoid(III) ions, are presented. Although the tetradentate ligand 2 - leads to an interesting complex [(2)(2-H)YCl 2 ) with yttrium-(III), a more general principle for the coordination of the metal ions by hydrazone-type ligands can be found with ligand 3, where 1:1 complexes are obtained with an

  The new pro-ligand 4-methyl-4′-(carbonylamino(2-(tert-butoxycarbonylamino)ethyl))-2,2′-bipyridyl (L1) has been prepared and used to synthesise the complex fac-ReICl(CO)3(L1) 1 and the complex salts [MII(bipy)2(L1)](PF6)2 (M = RuII8 or OsII15). Deprotection with trifluoroacetic acid affords the amine-functionalised derivatives fac-ReICl(CO)3(L2) 2, [MII(bipy)2(L2)](PF6)2 (M = RuII9 or OsII16) which react with the dianhydride of diethylenetriamine pentaacetic acid (DTPA) to give the binuclear complex fac-ReICl(CO)3}2(L3) 3 and the complex salts [MII(bipy)2}2(L3)](PF6)4 (M = RuII10 or OsII17). The latter react with salts Ln(OTf)3 to afford a series of 12 heterotrimetallic compounds that contain a lanthanide (Ln) ion in the DTPA binding site; fac-ReICl(CO)3}2(L3)LnIII (Ln = Nd 4, Er 5, Yb 6 or Y 7) and [MII(bipy)2}2(L3)LnIII](PF6)(OTf)3 (M = RuII, Ln = Nd 11, Er 12, Yb 13 or Y 14; M = OsII, Ln = Nd 18, Er 19, Yb 20 or Y 21). All of these trimetallic species display absorption bands ascribed to metal-to-ligand charge-transfer (MLCT) excitations, and luminescence measurements show that these excited states can be used to sensitise near-infrared emission from LnIII (Ln = Nd, Er or Yb) ions. Single crystal X-ray structures of L1 and [RuII(bipy)2(L2H)](H2PO4)3·(CH3)2CO·0.8H2O were obtained, the latter revealing the presence of H2PO4− counter anions, the source of which is presumed to be hydrolysis of PF6− ions.

  新的配体4-甲基-4′-(羰基氨基(2-(叔丁氧羰基氨基)乙基))-2,2′-联吡啶（L1）已经被制备，并用于合成配合物fac-ReICl(CO)3(L1)1和配合物盐[MII(bipy)2(L1)](PF6)2（M = RuII8或OsII15）。用三氟乙酸进行脱保护得到胺功能化的衍生物fac-ReICl(CO)3(L2)2，[MII(bipy)2(L2)](PF6)2（M = RuII9或OsII16），它们与二亚胺五乙酸（DTPA）的二酐反应，得到双核配合物fac-ReICl(CO)3}2(L3)3和配合物盐[MII(bipy)2}2(L3)](PF6)4（M = RuII10或OsII17）。后者与Ln(OTf)3盐反应，得到一系列12个含有镧系（Ln）离子的异三金属化合物；fac-ReICl(CO)3}2(L3)LnIII（Ln = Nd 4, Er 5, Yb 6或Y 7）和[MII(bipy)2}2(L3)LnIII](PF6)(OTf)3（M = RuII，Ln = Nd 11, Er 12, Yb 13或Y 14；M = OsII，Ln = Nd 18, Er 19, Yb 20或Y 21）。所有的这些三金属物种都显示出归因于金属到配体电荷转移（MLCT）激发的吸收带，发光测量表明这些激发态可以用于敏化LnIII（Ln = Nd, Er或Yb）离子的近红外发射。得到了L1和[RuII(bipy)2(L2H)](H2PO4)3·(CH3)2CO·0.8H2O的单晶X射线结构，后者揭示了存在H2PO4−反离子，其来源被认为是PF6−离子的水解。

According to transient absorption data, Er3+ and Yb3+ are sensitized via energy transfer from the triplet state of the β-triketonate ligands. On the other hand, energy transfer to Eu3+ seems to occur via an alternative pathway, possibly directly via the singlet state or through ligand to metal charge transfer states. The
