A rare supramolecular assembly (stairs) of (cyclic tellurane) 1,3-dihydro-2 lambda(4)-benzotellurole-2,2-diyldicinnamate [C8H8Te(OCOCH-CHC6H5)(2)] based on intermolecular and intramolecular Te-O secondary bonds and assisted by C-H-O hydrogen bonds

摘要

Stairs of cyclic tellurane (1,3-dihydro-2lambda(4)-benzotellurole-2,2-diyldicinnamate) [C8H8Te(OCOCH=CHC6H5)(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.
