A rare supramolecular assembly (stairs) of (cyclic tellurane) 1,3-dihydro-2λ4-benzotellurole-2,2-diyldicinnamate [C8H8Te(OCOCHdouble bond; length as m-dashCHC6H5)2] based on intermolecular and intramolecular Te–O secondary bonds and assisted by C–H–O hydr

Stairs of cyclic tellurane (1,3-dihydro-2λ4-benzotellurole-2,2-diyldicinnamate) [C8H8Te(OCOCHdouble bond; length as m-dashCHC6H5)2] 1 assisted by intermolecular Te–O secondary bonds, intramolecular Te–O secondary bonds and C–H–O hydrogen bonds have been obtained. 1 accounts for the rare example, in organotellurium chemistry, containing both intermolecular and intramolecular Te–O secondary bonds acting as crystal structure directors to yield stair type supramolecular association assisted by CH–O hydrogen bonds.
