Abstract
The new ditelluroethers m-C6H4(CH2TeMe)(2) and p-C6H4(CH2TeMe)(2) have been prepared in good yield from nucleophilic reaction of m- or p-C6H4(CH2Br)(2) and LiTeMe in THF solution. Reaction of the new ditelluroethers with MeI or I-2 affords the light yellow m- or p-C6H4(CH(2)TeMe(2)l)(2) or the red/orange m- or p-C6H4(CH2TeI2Me)(2), respectively in high yield. These compounds have been characterised by IR, H-1, C-13{H-1} and (12)'Te{(1) H} NMR spectroscopy and El mass spectrometry as appropriate. The crystal structures of the di-iodo, derivatives m-C6H4(CH(2)Tel(2)Me)(2), p-C6H4(CH2TeI2Me)(2) and the related Phl(2)Te(CH2)(3)Tel(2)Ph (prepared from PhTe(CH2)(3)TePh and diiodine in THF solution) are described. In each compound the TeI2 units are axial and significant intermolecular Te... I secondary contacts ( approximate to3.6-4.1 Angstrom) are evident, which link these covalent compounds into extended networks with each Te atom in a distorted 6-coordinate environment.
