Structures of tribenzylmethanol and 1,2,3-triphenyl-2-propanol

摘要

The tribenzylmethanol molecule, (PhCH2)3COH, has approximate\udthreefold symmetry in the solid state. The hydroxyl\udH atom is disordered unequally over three orientations\udand is not involved in hydrogen bonding. The 1,2,3-triphenyl-2-propanol molecule, Ph(PhCH2)2COH, crystallizes\udwith two molecules per asymmetric unit which\uddiffer slightly in conformation. In one of the molecules\udthe hydroxyl H atom is disordered equally over two sites,\udwhereas in the other molecule there is no disorder. As in\udthe tribenzylmethanol molecule, there is no intermolecular\udO--H...O hydrogen bonding, presumably because of\udthe steric bulk of the molecules and their packing which\udprevents the close approach of the O atoms of adjacent\udmolecules.
