title: N,N'-Dibenzyl-2,2'-(3,6-dioxaoctane-1,8-diyldi-oxy)dibenzamide.
abstract: The title compound, C(34)H(36)N(2)O(6), located on a center of inversion, crystallizes with one half-mol-ecule in the asymmetric unit. The dihedral angle between the benzene rings is 86.19 (2)°. An intra-molecular N-H⋯O hydrogen bond forms a six-membered ring; it affects the conformation of the mol-ecule which adopts a folded rather than open conformation. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions.
