Abstract

Complexation of the planar multidentate ligand 3,5-bis-(2-hydroxyphenyl)pyrazole (H3L) with manganese chloride leads to the formation of the polynuclear complex [MnIII 8L4O4(MeO)4(MeOH)8] (1). 1 has an octanuclear macrocyclic core in which the MnIII ions are bridged by four L molecules to form a ring type structure. Antiferromagnetic interactions were shown to be operative between metal centers.
