چکیده

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.

In the title compound, C(38)H(38)N(2)O(4), the 16 atoms comprising the four six-membered rings that are fused together are approximately coplanar (maximum r.m.s. deviation = 0.033 Å). The benzene rings at either ends are nearly perpendicular to the mean plane of the fused-ring system; one is aligned at 80.4 (1) ° and the other at 82.2 (1)°.

Triptycene-derived macrotricyclic polyether containing an anthracene unit as a powerful host for 1,2-bis(pyridium)ethane, diquat and 2,7-diazapyrenium salt.

Triptycene-derived macrotricyclic polyether containing an anthracene unit is a powerful host for 1,2-bis(pyridium)ethane, diquat and 2,7-diazapyrenium salt with association constants of the 1 : 1 complexes at >10(5) M(-1). Crystal structures showed that π-π stacking interactions between the host and the guests play an important role in the formation of the stable complexes.

In the mol-ecule of the title compound, C(24)H(20)F(2)N(6)O(4)·C(2)H(5)OH, the pyrimidine ring is oriented at dihedral angles of 42.64 (3) and 62.94 (3)° with respect to the benzene rings, while the dihedral angle between the benzene rings is 74.45 (3)°. The pyridine ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O and O-H⋯N hydrogen bonds link the mol-ecule...
