| Abstract |
The title compound 1,4,23,26,29,48-hexaaza-6,9:16,19:31,34:41,44-tetrabenzo-12, 15,37,40-tetraoxa-cyclodotetracontane-4,5,18,19,25,26,39,40-octaene 1 (C40H46N6O4) was synthesized by [2+2] condensation of diethylenetriamine with 4,4 -diformyl-diphenoxyethane (dialdehyde) in a mixed solvent of ethanol and tetrahydrofuran. The crystal data are: M-r = 674.83, triclinic, P(1) over bar, a = 5.8249(1), b 9.4114(8), c = 17.649(2) Angstrom, alpha = 79.310(7), beta = 5.397(4), gamma = 78.970(8)degrees, V = 932.1(1) Angstrom(3), Z = 1, D-c = 1.202 g/cm(3), F(000) = 360, mu(MoKalpha) 0.079 mm(-1), R = 0.0486 and wR = 0.1439. The title molecule has a crystallographic center symmetry. The distance between the two secondary amine nitrogen atoms is 18.890(3) Angstrom. |
