Structure and magnetism of a Mn(III)-Mn(II)-Mn(II)-Mn(III) chain complex
DOI: 10.1039/C3DT50940K, PaperRobert Uhrecky, Jan Moncol, Marian Koman, Jan Titis, Roman Boca
A novel tetranuclear manganese(II/III) complex with anions of pyridine-2,6-dicarboxylic acid (dipicolinic acid) has been synthesised and magneto-structurally characterised. The crystal structure of [MnII2MnIII2(dipic)6(H2O)4][middle dot]2CH3OH[middle dot]4H2O has been determined by single-crystal X-ray diffraction.
