N2 - The crystal structures of PhMeTeI2 (1), FcMeTeI2 (2) and [FcMe2Te]+I- (3), which are the products of iodomethylation of R2Te2 (R = Ph, ferrocenyl (Fc)) by MeI, are reported. Analysis of secondary interactions and packing patterns in 1-3 revealed Te⋯πPh chalcogen bonding in 1, unusual structural parallels between 2 and 3, and unprecedented isomorphic substitution in the crystals of 3 with an admixture of Te-I ionized molecules 2 [FcMeTeI+]I-. In summary, we are discussing the 3c-4e bonding model as a general, seamless scheme for the geometry and electronic structure of hypervalent tellurium atom coordination in both the isolated molecules and crystals, which overcomes the confusing division between the molecular and supramolecular geometry.
