Two Schiff bases, HL1[2-((3-(dimethylamino)propylimino)methyl)-5-bromophenol] and HL2[2-((2-(diethylamino)ethylimino)methyl)-6-methoxyphenol], have been employed to prepare two new octahedral iron(III) complexes, [Fe(HL1)2(N3)2]ClO4·2H2O (1) and [Fe(HL2)2(NCS)2]ClO4·H2O (2). Both complexes are characterized by spectral and elemental analyses. Single crystal X-ray diffraction studies confirm their structures. In both complexes, Schiff bases are trapped in their zwitterionic forms and coordinated to iron(III) only through the imine nitrogen and phenoxo oxygen, i.e., they behave as bi-dentate ligands, keeping the remaining potential donor sites pendant. The measurement of χMvs. T for both complexes shows a continuous increase in susceptibility as the temperature decreases. The χM·T values from 300 to 2 K and the shape of these curves for both complexes discard the existence of a high-spin/low-spin transition. The decrease in χM·T of 1 with temperature is more pronounced than that expected for a complex with a small zero-field splitting. The magnetic behavior of 1 is explained by proposing the existence of a physical mixture of S = 5/2 and S = 1/2 spins and the presence of zero-field splitting in the S = 5/2 species.

Two mononuclear cobalt(III) complexes, [Co(L1)(N3)2(deen)] (1) and [Co(L2)(N3)2(DMSO)] (2), where HL1 {2-(2-(diethylamino)ethyliminomethyl)-4-bromophenol} and HL2 {2-(2-(diethylamino)ethyliminomethyl)-6-methoxyphenol} are tridentate and tetradentate Schiff bases, respectively and deen is a bidentate chelating ligand, N,N-diethyl-1,2-diaminoethane, were prepared and characterized by elemental and spectral analysis. X-ray crystal structure determination confirmed their structures. Both complexes are meridional isomers. The solid state structures show the participation of the organic ligands in concurrent conventional and unconventional C-H. . .π interactions along with hydrogen bonding. The energetic features of these interactions have also been studied by means of DFT calculations.
