Chimeric supramolecular synthons in Ph₂Te₂(I₂)Se

Abstract

Iodination of Ph2Te2Se by molecular iodine is directed towards the Te atom and yields {diiodo[(phenyltellanyl)selanyl]‐λ4‐tellanyl}benzene, PhTeSeTeI2Ph or C12H10I2SeTe2. The molecule can be considered as a chimera of PhTeSeR, PhTeSeTePh and R′TeI2Ph fragments. The crystal structure features a complex interplay of the supramolecular synthons Te…π(Ph), Se…Te and I…Te, combining molecules into a three‐dimensional framework. Their combination affords long‐range supramolecular synthons which are fused in a way resembling the mythological chimera and could be defined as chimeric supramolecular synthons. The energies of the intermolecular interactions have also been calculated and analyzed.

Te⋯I secondary-bonding interactions in crystals containing tellurium(ii), tellurium(iv) and iodide atoms: supramolecular aggregation patterns, nature of the non-covalent interactions and energy considerations

“…Each of the independent tellurium(II) and tellurium(IV) atom participates in the formation of Te⋯I interactions The third one-dimensional aggregation is seen in the crystal of 5 which comprises binuclear molecules formulated as PhTe II (μ-Se)Te IV PhI 2 . 92 In terms of Te⋯I interactions, each independent tellurium atom forms two such interactions as does each of the two independent, tellurium(IV)-bound iodide atoms; all separations are long, Table 1. A non-symmetric, fourmembered {⋯Te IV I} 2 synthon is formed where tellurium(IV) atoms arranged in a zigzag fashion along the glide plane are bridged by the two independent iodide atoms.…”

Static and Dynamical Quantum Studies of CX3-AlX2 and CSiX3-BX2 (X = F, Cl, Br) Complexes with Hydrocyanic Acid: Unusual Behavior of Strong π-Hole at Triel Center

“…The origin of the contacts that were earlier observed in the solid state [2][3][4][5][6][7][8] became more understandable, which triggered searching for and examining (both theoretically and experimentally) new synthons grounded on the electron density donor-acceptor relations. The literature is crowded with examples of the role of σ-hole and π-hole interactions in steering the structural arrangement in crystal structures and acting as driving forces for the self-assembling of supramolecular architectures, even if only the last two years are considered [9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”
