Crystal structure of 2-[2-(2-aminophenoxy)ethoxy]-N-[(1E)-2,3,5,6,8,9,11,12-octahydro-1,4,7,1 0,13-benzopentaoxacyclopentadecin-15-ylmethylene]aniline

Abstract

The title compound, C29H34N2O7, is a substituted monotopic benzo-15-crown-5-ether ligand. It belongs to the space group P21/a with cell parameters a = 8.9857(6), b = 25.0353(17), c = 12.6979(9)Å and ß = 109.730(1)o. The intermolecular N-H·O hydrogen bonds are dominantly effective in stabilizing the crystal structure. The N-H·O intermolecular hydrogen bonds link the molecules, forming infinite one-dimensional chains running approximatelly parallel to the a-axis. The relative macrocyclic inner-hole size is estimated to be 1.44 Å. The substituent and benzocrown ether precursors about the C=N imine bond reveals a trans planar (1E) configuration. 2006 © The Japan Society for Analytical Chemistry.
