1:1 adduct of tris(4-hydroxy-3,5-dimethylbenzyl)amine and hexamethylenetetramine

The title compound {4,4',4 ''-(nitrilotrimethylene)tris(2,6-dimethylphenol)-1,3,5,7-tetraazatricyclo (1/1), C27H33NO3.C6H12N4} crystallizes in the space group <R(3)over bar>, with hydrogen-bonded layers perpendicular to the symmetry axes. All molecules lie on threefold rotation axes. Each triphenol molecule is hydrogen bonded to three hexamethylenetetramine molecules and each hexamethylenetetramine molecule is hydrogen bonded to three triphenol molecules. The hydrogen bonds are similar to those found in other adducts of hexamethylenetetramine with phenols.
