摘      要：Complexation of the planar multidentate ligand 3,5-bis-(2-hydroxyphenyl)pyrazole (H 3 L) with manganese chloride leads to the formation of the polynuclear complex [Mn Ⅲ 8 L 4 O 4 (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.
