N2 - The crystal structures of tellurium compounds frequently display intermolecular contacts between the chalcogen and atoms possessing lone pairs of electrons. Analysis of the data deposited in the Cambridge crystallographic database shows that the shortest secondary bonding interactions (SBIs) are formed when oxygen, nitrogen or chlorine are the donor atoms for SBIs. In addition, these SBIs are shortest when they occur opposite to a bond between tellurium and oxygen, nitrogen, fluorine, chlorine or the nitrile functional group. The structural motifs assembled in these systems fall within eight general categories, from single to multiple bonded supramolecular synthons. The use of multiple points of attachment between molecules leads, in principle, to stronger and more directional supramolecular synthons. The overall structures assembled by the most important tellurium-based supramolecular synthons and prospects for their application in crystal engineering are discussed.
