  Au(I) and Ag(I) formamidinate tetranuclear complexes and coordination polymers: Synthesis, structures and luminescent properties

  摘要：

  Reactions of AuCIS(CH3)(2) and Ag(I) salts (AgSCN, AgOAc and AgSbF6) with the lithiated formamidines afforded the tetranuclear complexes [Au-4(4-pyf)(4)]center dot 4CH(3)OH [4-Hpyf = N,N'-bis(pyridine-4-yl)formamidine], 1, [Au-4(pmf)(4)] [Hpmf = N,N'-bis(pyrimidine-2-yl)formamidine], 2, and [Ag-4(pmf)(4)], 3, and the coordination polymers [Ag-2(OAc)(4-pyf)](n), 4, and {[Ag-2(4-pyf)(2)]center dot THF}(n), 5, which have been structurally characterized by X-ray crystallography. The intramolecular Au center dot center dot center dot Au separations in 1 and 2 are in the range 2.8832(2)-3.3338(10) angstrom and the Ag center dot center dot center dot Ag separations in 3-5 are 2.7927(3)-2.9819(19) angstrom, indicating the existence of aurophilicity and argentophilicity, respectively. Complex 3 is a unique tetranuclear complex of the type Ag-4(form)(4) in which "form" represents the formamidinate ligands. The short lifetimes of 1.06-49.15 ns for 1-5 indicate that the emissions belong to fluorescence. Moreover, complex 4 emits white luminescence in the solid-state and the CIE coordinate appears at (0.30, 0.38), which represents the first single-emitting component white phosphor in the class of formamidinate coordination polymers.

  A series of dimolybdenum complexes containing mixed formamidinate ligand are discussed. The reactions of trans-Mo-2(O2CCH3)(2)(o-DMophF)(2) [o-HDMophF=N,N'-di(2-methoxyphenyl)formamidine] with N,N'-di(2-pyridyl)formamidine (HD pyF), N,N'-di(2-pyrimidyl)formamidine (HDpmF) and N,N'-di(6-methyl-2-pyridyl)formamidine (HDMepyF), in refluxing CH2Cl2 afforded the complexes, traps-Mo-2(O2CCH3)(DpyF)(o-DMophF)(2) (1), trans-Mo-2(O2CCH3)(DpmF)(o-DMophF)(2) (2), and trans-Mo-2(O2CCH3)(DMepyF)(o-DMophF)(2) (3), respectively. The o-DMophF(-) and DMepyF(-) ligands in these complexes adopt the s-cis, s-trans conformation, resulting in Mo-O short distances [2.889 (3) and 2.861(2) Angstrom for 1; 2.880(3) and 3.024(4) Angstrom for 2], while the DpyF(-) ligand adopts the s-cis, s-trans conformation, resulting in a Mo-N [3.208(4) Angstrom] and a Mo-H [2.90 (3) Angstrom] short distances. The reactions of trans-Mo-2(O2CCH3)(2)(o-DMophF)(2) with HDMepyF in CH3CN gave complexes 3, trans-Mo-2(O2CCH3)(DMepyF)(2)(o-DMophF) (4), and trans-Mo-2(DMepyF)(2)(o-DMophF)(2) (5). The o-DMophF(-) ligands in 4 and 5 adopt the s-cis, s-cis conformation while DMepyF(-) assumes an s-cis, s-trans conformation. Complexes 1-5 are the first dimolybdenum complexes containing mixed formamidinate ligands. (C) 2003 Elsevier B.V. All rights reserved.
