Bis(2-pyridyl)ditellane as a Precursor for [HgTe]-Based Clusters and Zwitterionic Compounds

Adamantane-type clusters: compounds with a ubiquitous architecture but a wide variety of compositions and unexpected materials properties

“…With mercury, the neutral compounds [(HgPPh3)2(HgX)2(Te o Py)6] (449-451, X = Cl, Br, I; o Py = orthopyridyl) and [(HgPPh3)2(HgSePh)2(SePh)6] (452) with mixed terminal ligands were obtainable when using halide or acetate mercury salts. [233,234] A complex precursor [M(L)2(ClO4)2] (M = Cd, Hg; L = PPh3, PEt3, AsPh3) in combination with M(ER)2 (E = S, Se) and free L leads to cationic clusters in [(ML)4(ER)6][ClO4]2 (453-464, Figure 10). [235][236][237] With certain L and R combinations, this can lead to clusters with a few terminally uncoordinated M sites, which do not, however, influence the charge.…”

Bis(2-pyridyl)ditellane as a precursor to CoII, CuI and CuII complex formation: structural characterization and photocatalytic studies

“…The bis(2-pyridyl)ditellane (2-PyTe) 2 ligand was prepared according to the literature procedures. 15 All other analytical grade reagents and solvents were obtained commercially from Sigma-Aldrich or Vetec and used as received. All coordination compounds (1)(2)(3)(4) were obtained as crystalline solids by filtration from the mother liquor followed by washing the crystals with methanol to remove the unreacted starting materials and side products.…”

“…Pyridyltellurium moieties form an interesting class of ligands due to the different nature of the Te and N donor atoms, which can provide products with a wide structural diversity. [15][16][17] Generally, the reaction of diarylditellane with metal derivatives results in the Te-Te bond cleavage to yield tellurolato metal complexes. For example, Jungfer and co-workers lately described the reactions of Schiff base-substituted ditellane with Ni II , Pd II , Pt II and Re V phosphine complexes.…”

Oxidorhenium(V) and Rhenium(III) Complexes with Arylselenolato and ‐tellurolato Ligands

“…Some of them are capable of reductive N 2 splitting to nitrido complexes and subsequent formation of ammonia. 4 Among the ligands used for such applications, aromatic organochalcogenolates (ArE − with E=O, S, Se or Te) represent an interesting and versatile class [6–9] . The coordination chemistry of rhenium complexes containing organothiolato ligands is well known with thoroughly performed structural studies and well explored synthetic pathways [10–16] .…”

“…4 Among the ligands used for such applications, aromatic organochalcogenolates (ArE À with E=O, S, Se or Te) represent an interesting and versatile class. [6][7][8][9] The coordination chemistry of rhenium complexes containing organothiolato ligands is well known with thoroughly performed structural studies and well explored synthetic pathways. [10][11][12][13][14][15][16] In contrast, there is a substantial lack of studies with monodentate phenolates or with ligands coordinating through heavier chalcogen donor atoms.…”
