Abstract
Determination of the crystal structure of the title compound [systematic name: 9,25-dibenzyl-4,4,15,15,20,20,31,31-octamethyl-3,5,14,16,19,21,30,32-octaoxa-8,11,24,27-tetraazapentacyclo[27.3.0.0(2,6).0(13,17).0(18,22)]dotriacontane-7,10,23,26-tetrone], C42H56N4O12, a cyclic tetramer, established the relative stereochemistry of its ten stereogenic C atoms; an interesting saddle-like conformation is adopted. There are two molecules in the asymmetric unit. With the exception of the phenyl and isopropylidene groups, the molecules are related by a non-crystallographic twofold rotation axis. There are varying degrees of disorder in the isopropylidene groups.
