“…The Te–Te distance in 2c (3.33 Å) is much shorter and indicates a relatively strong intermolecular Te–Te bonding interaction with the formation of dimeric species. It is longer than typical Te–Te single bond lengths between two-coordinate Te atoms or in coordination compounds of ditellanes (∼2.7 Å, Te ∞ , Me-Te-Te-Me, (CO) 5 M←(H 5 C 6 )Te-Te(C 6 H 5 )→M(CO) 5 , M = Cr, W), ,− but significantly shorter than observed for typical closed-shell interactions. , Distances similar to those of 2c were found for bonds between three-coordinate Te atoms as in Mes 2 Te-Te(I)Mes or compounds with strained geometries. − The bonding situation in these compounds is completely different from that of 2c . The short Te–Te distances in these cases are forced by an 1,8-position of the Te atoms on a naphthalene backbone or favored by electron-withdrawing iodine atoms bonded to Te − or a cationic tellurium species in the bridging position between two Te atoms .…”

Chalcogen Capture by an Al/P-Based Frustrated Lewis Pair: Formation of Al-E-P Bridges and Intermolecular Tellurium–Tellurium Interactions

et al. 2015

Reaction of the Al/P-based frustrated Lewis pair (FLP) Mes 2 P-C(CH-C 6 H 5 )-Al(CMe 3 ) 2 1 with heavier chalcogens (E = S, Se and Te) yielded by oxidation of the P atoms the respective phosphorus(V) compounds Mes 2 P(E)-C(CH-C 6 H 5 )-Al(CMe 3 ) 2 (2a, E =S, 2b, E = Se, 2c, E = Te) in good yield. The chalcogen atoms were coordinated to the Lewis-acidic Al atoms, which, in the case of the dark red Te compound 2c, resulted in a stabilization of the P−Te bond. Unique fourmembered, slightly puckered P-C-Al-E heterocycles were formed with P−E bond lengths in the normal range of terminal chalcogen atoms and comparatively long Al−E bonds, which are consistent with relatively weak Al−E interactions. Both the Se and more pronounced the Te compound formed dimers in the solid state as a result of closed-shell chalcogen−chalcogen interactions. While the Se···Se distance was only slightly shorter than the sum of the van der Waals radii (3.8 Å), the Te···Te separation (3.33 Å) was relatively short and in the characteristic range of significant intermolecular Te···Te interactions, which may result from a double donor−acceptor interaction. Quantum chemical calculations suggested a Te−Te bond energy of about −16.5 kcal/mol. The corresponding oxygen derivative could not be isolated in a pure form, but it may be formed by thermal decomposition of the new FLP adduct 1·ONMe 3 .

“…[23] The AgÀ N bond lengths 2.363(6)/2.411(7) Å, 2.383(6)/2.449(6) Å are shorter than the reported acetonitrile coordinated telluroether silver complex 2.573(5)/2.253(4) Å.

The tetradentate organotelluroether (C 9 H 6 NTe) 2 CH 2 ligand has been synthesized and its coordination behaviour with a stoichiometric amount of copper(II) and silver(I) perchlorate and triflate salts has been experimentally investigated. The isolated ligand and metal complexes are characterized by multinuclear ( 1 H, 13 C, 125 Te) NMR spectroscopy, single crystal X-ray diffraction, and DFT calculations. The X-ray analysis revealed the formation of self-assembled bimetallic complexes with the molecular formula of 2[M(C

Chemistry of organotellurium compounds has developed very rapidly during the recent decades. Tellurium reagents find uses in synthetic organic chemistry. Organometallic complexes with tellurolato or telluroether ligands show potential application in the fabrication of new materials for electronic devices. The present review emphasizes the preparation and structural characterization of some main classes of organic tellurium compounds and their organometallic complexes that are deemed of interest for inorganic chemists.
