| Description
| - Eight mononuclear Fe(III) Schiff base complexes with the general formula [Fe(L5)(L1))].S (H2L5 = pentadentate Schiff-base ligand, L1 = a pseudohalido ligand, and S is a solvent molecule) are reported. Different aromatic 2-hydroxyaldehyde derivatives were used in combination with a non-symmetrical triamine 1,6-diamino-4-azahexane to synthesize the H2L5 Schiff base ligands. The consecutive reaction with iron(III) chloride resulted in the preparation of the [Fe(L5)Cl] precursor complexes which were left to react with a wide range of the L1 pseudohalido ligands. The low-spin compounds were prepared using the cyanido ligand: [Fe(3m-salpet)(CN)].CH3OH (1a), [Fe(3e-salpet)(CN)].H2O (1b), while the high-spin compounds were obtained by the reaction of the pseudohalido (other than cyanido) ligands with the [Fe(L5)Cl] complex arising from salicylaldehyde derivatives: [Fe(3Bu5Me-salpet)(NCS)] (2a), [Fe(3m-salpet)(NCO)].CH3OH (2b) and [Fe(3m-salpet)-(N3)] (2c). The compounds exhibiting spin-crossover phenomena were prepared only when L5 arose from 2-hydroxy-1-naphthaldehyde (H2L5 = H2napet): [Fe(napet)(NCS)].CH3CN (3a, T(1/2) = 151 K), [Fe(napet)(NCSe)].CH3CN (3b, T(1/2) = 170 K), [Fe(napet)(NCO)] (3c, T(1/2) = 155 K) and [Fe(napet)(N(3))], which, moreover, exhibits thermal hysteresis (3d, T(1/2)up arrow = 122 K, T(1/2)down arrow = 117 K). These compounds are the first examples of octahedral iron(III) spin-crossover compounds with the coordinated pseudohalides. We report the structure and magnetic properties of these complexes.
