An antiferromagnetic {Mn8} ring supported by planar multidentate ligands

Complexation of the planar multidentate ligand 3,5-bis-（2-hydroxyphenyl）pyrazole （H3L） with manganese chloride leads to the formation of the polynuclear complex [MnIHsL4Oa（MeO）a（MeOH）8] （1）. 1 has an octanuclear macrocyclic core in which the MnnI ions are bridged by four L molecules to form a ring t...

Zusammenfassung:	Complexation of the planar multidentate ligand 3,5-bis-（2-hydroxyphenyl）pyrazole （H3L） with manganese chloride leads to the formation of the polynuclear complex [MnIHsL4Oa（MeO）a（MeOH）8] （1）. 1 has an octanuclear macrocyclic core in which the MnnI ions are bridged by four L molecules to form a ring type structure. Antiferromagnetic interactions were shown to be op- erative between metal centers.
