N2 - Transition-metal complexes of a tetraaza macrocyclic ligand obtained from Schiff base condensations of 2-amino-5-methylbenzaldehyde were synthesized and characterized (M(MeTAAB)2+, M = Co3+, Ni2+, Cu2+, Zn2+, Pd2+, and Pt2+). The crystal structure of [Cu(MeTAAB)(NO3)][NO3] was determined by using X-ray crystallographic techniques. The complex crystallizes in the space group P21/c with unit cell dimensions a = 13.136 (6) Å, b = 17.294 (7) Å, c = 17.391 (4) Å, and β = 127.66 (2)°. The coordination sphere of the copper ion is six-coordinate, N4O2, with a symmetrically bidentate nitrate making the overall geometry a bicapped square pyramid. The macrocyclic ligand is, as expected, distinctly saddle shaped, with S4 symmetry.
