title: 2,3,4,5-Tetra-O-acetyl-1,6-di-O-(triphenylmethyl)-D-mannitol.
abstract: The central six-C-atom chain of the title compound, C52H50O10, adopts a nearly planar extended conformation free from C parallel C, C parallel O and O parallel O 1,3-parallel interactions. The three torsion angles formed by these atoms have values of 177.4 (2), 174.2 (2) and -178.0 (2) degrees. The bulky triphenylmethyl groups, which are oriented gauche to their neighboring acetoxy groups with O--C--C--O torsion angles of -69.8 (2) and -63.0 (2) degrees, cause no distortion of the bond lengths and bond angles of the sugar moiety.
