Abstract

The various metal-porphyrin orbital interactions taking place in highly saddled low-spin iron(III) porphyrin complexes are studied. These complexes are found to exhibit a very small substituent effect on the chemical shifts because of the interaction of the unpaired electrons with porphyrin rings.

4. Ferro- and ferrimagnetic chains of hin-bridged copper(II) and manganese(II) and hnn-bridged manganese(II) complexes (hin= 4,4,5,5-tetramethylimidazolin-1-oxyl; hnn= 4,4,5,5-tetramethylimidazolin-1-oxyl 3-oxide)

Abstract

Research has been conducted on 4,4,5,5-tetramethylimidazolin-1-oxyl and 4,4,5,5-tetramethylimidazolin-1-oxyl 3-oxide. The authors have investigated the utility of these compounds as mu-1,4 and mu-1,5 bridging ligands with unpaired electron in development of metal-radical hybrid magnets.

Abstract

Complexation of copper(II) bromide and chloride with 4-pyrimidinyl nitronyl nitroxide (4PMNN) as a bridging ligand gave discrete hexanuclear complexes carrying 12 spins, [CuX(sub 2).(4PMNN)](sub 6) (X = Br, Cl), which crystallize in a trigonal space. The magnetic behavior is interpreted as the simultaneous presence of ferro and antiferromagnetic couplings.
