N-[(2-Phenyl-2H-1,2,3-triazol-4-yl)methylene]-2-(2-(2-phenyl-2H-1,2,3-triazol-4-yl)-3-{2-[(2-phenyl-2H-1,2,3-triazol-4-yl)methyleneamino]ethyl}imidazolidin-1-yl)ethanamine.

The reaction of 2-phenyl-2H-1,2,3-triazole-4-carbaldehyde with triethylenetetramine leads to the formation of a new binucleating ligand, viz. the title compound, C(33)H(33)N(13), demonstrating that this structure has the potential for more flexible rational design and tailoring. The title molecule is rendered quite rigid by the formation of a five-membered imidazolidine ring and there are four independent instances of pi-pi interactions. Both sides of each of the three aromatic arms take part in these interactions, forming a neat three-dimensional array structure.
