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