Mannich reaction of 2-Amino propanol, 2-tertbutyl-4-methylphenol, and formaldehyde in the ratio of 1:2:2 provides a new compound, N-(1-propanol)-N,N-bis-((3-tert-butyl-5-methyl-2-hydroxybenxyl)amine (H 3 L), which has been characterized by X-ray crystallography and elemental analysis. In the presence of Et 3 N, the reaction of H 3 L and FeCl 3 Á6H 2 O gives a dinuclear Fe(III) complex [Fe 2 L 2 ] 1, which has been characterized by X-ray crystallography, magnetic measurement, and cyclic voltammetry. The value of l eff at room temperature (5.97 l B ) is much less than the expected spin-only value (8.37 l B ) of two high spin (hs) Fe 3? (S = 5/2) ions [l = g[ P ZS(S ? 1)] 1/2 ], indicating there are strong coupling interactions between Fe 3? ions. The magnetic behavior of 1 denotes the occurrence of intramolecular antiferromagnetic interactions (J = -13.35 cm -1 ). CV of 1 reveals two reversible waves at 0.433 and 1.227 V versus AgCl/Ag, which can be ascribed to the successive redox

The reaction of methyl anthranilate, sodium nitrite, and 2-aminopyridine produces a triazenide, namely,
