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)-tricyclo22,2,2,211,14] triaconta-1,11,13,24,27,29-hexaene, crystallizes in the monoclinic space group P21/c with a = 8.700(2) Å, b = 18.301(4) Å, c = 11.766(2) Å, = 108.57(2)°. The two hydroxyethyl pendants are at the opposite sides of the macrocyclic plane. Benzene rings in macrocycle are parallel and exist the - weak interaction with distance of 4.28 Å. The crystal packing of the macrocycle is stabilized by the hydrogen bonds. |
