1,15:21,35-Bis(oxydiethyl-ene)-5,8,11,18,25,28,31,38-octa-oxa-1,15,21,35-tetra-azacyclo-tetra-decane-16,20,36,40-tetra-one-benzene (1/2): a macrotricyclic tetra-lactam.

ABSTRACT: The macrotricyclic title compound, C(36)H(64)N(4)O(14)·2C(6)H(6), is located on a crystallographic center of symmetry. The mol-ecule has four tertiary amide bridgehead atoms and consists of two unsymmetrical 20-membered diaza-tetra-oxamacrocycles (N(2)O(4) donor atom set) connected through the N atoms by two lateral oxydiethyl-ene bridges. The bridging subunits, together with the short bridging strand (NCCOCCN) from each monocycle, define a 24-membered ring (N(4)O(4) donor atom set) that forms a central cavity.
