New derivatives of the macrocyclic ligand TAAB, tetrabenzo [i>/J,«][1, 3, 5, 9] tetraazacyclohexadecine, havebeen prepared in which the substituents are bound by CC linkages. They are produced by the displacement of diethylamide groups from the azomethine carbon atoms of TAAB with the enolate of acetone. The new compounds have the composition M11-(TAAB)(CH2COCH3) 2. An X-ray structure determination (Ni2+ complex) shows the crystals to be triclinic, p0= 1.37 g cm™ 3 (flotation), pc= 1.363 g cm™ 3, space group El, Mo, 0.7107 Á. Thestructure refined to R= 0.061 and Rw= 0.081. The two enolate groups have added to trans¡ mine-carbon atoms but the substituents are on the same side of the approximateNiN4 plane. The overall conformationof the macrocycle is saddle shaped and bond distances confirm the general electronic structures assigned to this class of nucleophilic ligand adducts of TAAB.
