The synthesis and characterization of copper(II), manganese(III), and iron(III) complexes [Cu2(L1)(OAc)Cs2(MeOH)2]n (1), [Mn2(H3L1)2(OMe)2]·2MeOH (2), [Fe2(H3L1)2(Hpz)4](ClO4)2·2CH3CN (3), and [Fe2(H3L3)2(OMe)2]·8MeOH (4) of potentially pentaanionic heptadentate ligands,2‐hydroxy‐N‐{2‐hydroxy‐3‐[(2‐hydroxybenzoyl)amino]propyl}benzamide (H5L1) and 2‐hydroxy‐N‐{3‐hydroxy‐5‐[(2‐hydroxybenzoyl)amino]pentyl}benzamide (H5L3), are reported. The crystal structure and magnetic properties of these complexes have been determined. In complex 1, the ligand H5L1 acts as a heptadentate, fully deprotonated ligand, [L1]5–. In complexes 2, 3, and 4, H5L1 (2, 3) and H5L3 (4) act as tetradentate, partially deprotonated ligands, [H3L1]2– and [H3L3]2–.In complex 1, anionic [Cu2(L1)(OAc)]2– and cationic [Cs(MeOH)]+ units are linked through a quadruply bridging acetate ion and through the phenoxido‐oxygen and amido‐oxygen donor atoms of [L1]5– to yield a 2D polymeric network. Complexes 2–4 form extended supramolecular networks. Magnetic susceptibility data evidence antiferromagnetic interactions for 1, 2, and 4. The Fe···Fe distance is too long to allow measurable magnetic interactions in complex 3. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

“…20 However, the analogous diamido macrocycles are known to be more structurally flexible and they can deviate from a nonplanar coordination. 21 If such conformational changes perturb substrate approaches toward the oxidizing intermediate, then communication with the chiral cyclohexane bridge may be prevented.…”
