Abstract
Elemental Te inserts across the C–I bond of in situ generated iodo derivatives of 1,3-dibromopropane, (trimethylsilyl)methyl iodide, benzyl chloride and m-nitro-benzyl bromide to give rise the , (Me3SiCH2)2TeI2, (C6H5CH2)2TeI2, and (m-NO2-C6H4CH2)2TeI2 molecules in good yield respectively. These molecules are characterised by 1H NMR and elemental analysis techniques. Among these (C6H5CH2)2TeI2 and (m-NO2-C6H4CH2)2TeI2 molecules are also characterized by single-crystal X-ray studies. In the packing diagram of (C6H5CH2)2TeI2, there are intermolecular Te⋯π-phenyl interaction (3.768 Å) between the tellurium atoms and phenyl rings of adjacent molecule. The crystal packing of (m-NO2–C6H4CH2)2TeI2, displays an interesting supramolecular synthon. This synthon is based on reciprocal several C–H⋯O, C–H⋯I Hydrogen bonding interactions along with Te⋯I Secondary bonding interactions.
期刊介绍:
Journal of Chemical Crystallography is an international and interdisciplinary publication dedicated to the rapid dissemination of research results in the general areas of crystallography and spectroscopy. Timely research reports detail topics in crystal chemistry and physics and their relation to problems of molecular structure; structural studies of solids, liquids, gases, and solutions involving spectroscopic, spectrometric, X-ray, and electron and neutron diffraction; and theoretical studies.
