Abstract
The reactions of the (triflato)[(meso-tetra(para-methoxyphenyl)porphyrinato)]manganese(III) ([MnIII(TMPP)(SO3CF3)] with an excess of 4-dimethylaminopyridine (DMAP) and hexamethylenetetramine (HMTA) have been examined. These reactions yield crystalline [MnIII(TMPP)(DMAP)2](0.1Cl)(0.9SO3CF3)•CHCl3 (I) and [MnIII(TMPP)(HMTA)2](SO3CF3)• CH2Cl2 (II), respectively. I-II exhibit hyper d-type electronic spectra characteristic of high-spin (S = 2) Mn(III) metalloporphyrins with very redshifted Soret bands. The crystal structures of the solid I-II complexes were determined by X-ray single-crystal diffraction and elucidated by Hirshfeld surface approach. The cyclic voltammograms of I-II are the one of a hexacoordinated Mn(III) porphyrins with neutral axial ligand. Bioactivity of the H2TMPP free base, the [MnIII(TMPP)(SO3CF3)] starting material and complexes I-II, was assessed by a set of in vitro tests checking for antioxidant, antibacterial and antifungal (against several strains) effects.

The reactions of the (triflato)(meso-tetra(para-methoxyphenyl)porphyrinato)manganese(III) ([MnIII(TMPP)(SO3CF3)] complex with an excess of 4-dimethylaminopyridine (DMAP) and hexamethylenetetramine (HMTA) have been examined. These reactions yield crystalline [MnIII(TMPP)(DMAP)2](0.1Cl)(0.9SO3CF3)•2CHCl3 (I) and [MnIII(TMPP)(HMTA)2](SO3CF3)•2CH2Cl2 (II) complexes, respectively. The hyper d-type electronic spectra of I-II are characteristic for high-spin (S = 2) Mn(III) metalloporphyrins with very redshifted Soret bands. A cyclic voltammetry investigation was carried out on these two Mn(III) coordination compounds. The crystal structures of the solid complexes I-II were determined by X-ray single-crystal diffraction and elucidated by Hirshfeld surface approach. Furthermore, bioactivity of the H2TMPP free base, the [MnIII(TMPP)(SO3CF3)] starting material and complexes I-II, was assessed by a set of in vitro tests checking for antioxidant, antibacterial and antifungal (against several strains) effects.
