The isolation, structural characterization and electronic properties of three new six-coordinated Mn(III) complexes, [Mn(bpea)(F)(3)] (1), [Mn(bpea)(N(3))(3)] (2), and [Mn(terpy)(F)(3)] (3) are reported (bpea = N,N-bis(2-pyridylmethyl)-ethylamine; terpy = 2,2':6',2' '-terpyridine). As for [Mn(terpy)(N(3))(3)] (4) (previously described by Limburg J.; Vrettos J. S.; Crabtree R. H.; Brudvig G. W.; de Paula J. C.; Hassan A.; Barra A-L.; Duboc-Toia C.; Collomb M-N. Inorg.

High-spin chloro mononuclear MnIII complexes: a multifrequency high-field EPR study.
This study confirms the previous results and shows that: i) the sign of D is correlated with the nature of the tetragonal distortion; ii) the magnitude ofD is not sensitive to thenature of the anions in the authors' series of rhombic complexes, contrary to the porphyrinic systems; iii) the E term increases when the ligand-field strength of the equatorial ligands decreases.
Definition of magneto-structural correlations for the MnII ion.
An investigation of the electronic properties of the high spin mononuclear MnII complexes reveals that D is sensitive to the coordination number (5 or 6) of the MnII ion, consistent with the relative ligand fields of OH(-) versus H2O.
An unusual stable mononuclear Mn(III) bis-terpyridine complex exhibiting Jahn-Teller compression: electrochemical synthesis, physical characterisation and theoretical study.
The mononuclear manganese bis-terpyridine complex, containing Mn in the unusual +III oxidation state, has been isolated and characterised and X-ray analysis unambiguously revealed its tetragonally compressed octahedral geometry and high-spin character.
Field-Induced Slow Magnetic Relaxation in a Mononuclear Manganese(III)-Porphyrin Complex.
Structural, magnetic, and electronic characterizations were carried out by means of single-crystal diffraction studies, variable-temperature direct- and alternating-current measurements and high-frequency and -field EPR spectroscopic analysis followed by quantum-chemical calculations.
Synthetic, structural, spectroscopic and theoretical study of a Mn(III)-Cu(II) dimer containing a Jahn-Teller compressed Mn ion.
The heterobimetallic complex [Cu(II)Mn(III)(L)(2)(py)(4)](ClO(4))·EtOH (1) built using the pro-ligand 2,2'-biphenol (LH(2), contains a rare example of a Jahn-Teller compressed Mn(III) centre, with magnetisation measurements at low temperatures and high fields suggesting significant anisotropy.
