Abstract
The new macrocyclic compound bearing hydroxyethyl pendant arms containing p -xylyl spacers, 3,6,9,16,19,22-hexaaza-6,19-bis(2-hydroxyethyl)-tricyclo[22 ,2,2,2(11.14)] triaconta-1,11,13,24,27,29-hexaene, crystallizes in the mono clinic space group P2(1)/c with a = 8.700(2) Angstrom, b = 18.301(4) Angstr om, c = 11.766(2) Angstrom, beta = 108.57(2)degrees. The two hydroxyethyl p endants are at the opposite sides of the macrocyclic plane. Benzene rings i n macrocycle are parallel and exist the pi-pi weak interaction with distanc e of 4.28 Angstrom. The crystal packing of the macrocycle is stabilized by the hydrogen bonds.
