  Zinc Chalcogenolate Complexes as Precursors to ZnE and Mn/ZnE (E = S, Se) Clusters

  摘要：

  The ternary clusters (tmeda)(6)Zn14-xMnxS13Cl2 (1a-d) and (tmeda)(6)Zn14-xMnxSe13Cl2 (2a-d), (tmeda = N,N,N',N'-tetramethylethylenediamine; x approximate to 2-8) and the binary clusters (tmeda)(6)Zn14E13Cl2 (E = S, 3; Se, 4;) have been isolated by reacting (tmeda)Zn(ESiMe3)(2) with Mn(II) and Zn (II) salts. Single crystal X-ray analysis of the complexes confirms the presence of the six "(tmeda)ZnE2" units as capping ligands that stabilize the clusters, and distorted tetrahedral geometry around the metal centers. Mn(II) is incorporated into the ZnE framework by substitution of Zn(II) ions in the cluster. The polynuclear complexes (tmeda)(6)Zn12.3Mn1.7S13Cl2 1a, (tmeda)(6)Zn12.0Mn2.0Se13Cl2 2a, and (tmeda)(6)Zn8.4Mn5.6Se13Cl2 2d represent the first examples of "Mn/ZnE" clusters with structural characterization and indications of the local chemical environment of the Mn(II) ions. The incorporation of higher amounts of Mn into 1d and 2d has been confirmed by elemental analysis. Density functional theory (DFT) calculations indicate that replacement of Zn with Mn is perfectly feasible and at least partly allows for the identification of some sites preferred by the Mn(II) metals. These calculations, combined with luminescence studies, suggest a distribution of the Mn(II) in the clusters. The room temperature emission spectra of clusters 1c-d display a significant red shift relative to the all zinc cluster 3, with a peak maximum centered at 730 nm. Clusters 2c-d display a peak maximum at 640 nm in their emission spectra.

  Coordination Complexes of Zinc with Reactive ESiMe₃ (E = S, Se, Te) Ligands

  摘要：

  The complexes (N,N'-tmeda)Zn(ESiMe3)(2) (E = S, 1a; E = So, 2a; E = Te, 3a) and (3,5-Me-2-C5H3N)(2)Zn(ESiMe3)(2) (E = S, 1b; E = Se, 2b; E = Te, 3b) have been prepared in high yield by the reaction of E(SiMe3)(2) with (N,N'-tmeda)Zn(OAc)(2) (4a) and (3,5-Me-2-C5H3N)(2)Zn(OAc)(2) (4b), respectively. Complexes 1-3 have been characterized spectroscopically and by means of single-crystal X-ray diffraction. All six complexes exist in the solid state as monomeric species with terminally bonded trimethylsilylchalcogenolate moieties and a distorted tetrahedral geometry of the zinc center.
