“…The bis(acetylacetonato) Mn(III) complexes with axial halo-or pseudo-halo groups, i.e. Cl À , Br À , N À 3 or NCS À , serve as useful intermediates for Mn(III) porphyrins [27]. For preparation of chloro-complex, 0.979 g (0.003 mol) of [Mn III (acac) 2 Cl] and 2.5 g (0.003 mol) of H 2 TMPP were dissolved in 150 mL of glacial acetic acid containing 45 mL of acetic anhydride and refluxed for 4 h on a hot plate.…”

The present work describes the synthesis and characterization of a few Mn(III) porphyrins with ethylenediamine. A new series of high-spin Mn(III) porphyrins having general formula [Mn(TMPP)X] and [Mn(TMPP)X(en)], where TMPP ¼ tetra-p-methoxyphenylporphinato ligand, X ¼ Cl À , Br À , N À 3 or NCS À and en ¼ ethylenediamine. Molar conductance values of these complexes show their non-electrolytes in ethyl alcohol. These complexes have been characterized by U.V., I.R., ESI-mass spectra, elemental analyses and magnetic susceptibility measurements. The tentative structures have also been proposed.

“…Thermogravimetric analyses of the manganese(III) complexes indicate the presence of various levels of water molecules per manganese atom, which are lost at ca. 85-250°C [20,21]. It means that all of the complexes have coordinated water in their structures.…”

New series of manganese(III) complexes and amino acid Schiff bases have been prepared from 2-hydroxy-1-naphthaldehyde and a-amino acids [L-aspartic acid (Asp), L-asparagine (Asn), L-glutamic acid (Glu) and L-glutamine (Gln)]. The structures of the ligands and manganese complexes were identified using elemental analyses, i.r, electronic spectra, 1 H-n.m.r spectra, magnetic moment measurements and thermogravimetric analyses (t.g.a). The results suggest that H 2 L 1 : [N-(2-hydroxy-1-naphthylidene) aspartic acid] and H 2 L 3 : [N-(2-hydroxy-1-naphthylidene)glutamic acid] Schiff bases behave as trianionic tetradentate species and coordinate to Mn(III) ion according to the general formula [MnL] AE xH 2 O complexes. But, H 2 L 2 : [N-(2-hydroxy-1-naphthylidene) asparagine] and H 2 L 4 : [N-(2-hydroxy-1-naphthylidene)glutamine] Schiff bases behave as dianionic tridentate and coordinate to Mn(III) ion in the general formula for [MnL(OOCH 3 )] AE xH 2 O complexes.

A novel series of Mn III complexes with 5,10,15,20-tetra(p-tolylporphine) and 1,6-diaminohexane has been synthesized. These complexes have been characterized by UV/Vis, IR, ESI-mass spectra, elemental analysis, conductivity and magnetic susceptibility measurements. These Mn III porphyrins exhibited a blue shift in soret band in comparison to non-metallated porphyrins. The molar conductance values of these complexes show their non-electrolytic nature in ethanol. The tentative structures have also been proposed. All the complexes have good level of water solubility due to which they may have medicinal as well as other valuable biological applications.
