Abstract: Atetranuclear Mn(Ⅳ) complex [L4Mn4O6](ClO4)452H2O (L=tacn)was synthesized from Mn(CH3COO)254H2O, tacn and NaClO4 and characterized by XRD. The compound crystallizes in monoclinic system, space group P2-1/n, with a=2.1335(6) nm, b=1.1387(3) nm, c=2.1788(6) nm, β=67.40(3)°, V=4.928(2) nm3, Z=4, R=0.0620. Magnetic investigations reveal a weak ferromagnetic property with J=8.8 cm-1.

Key words: Tetranuclear Mn (Ⅳ) complexes, Macrocyclic ligand, Crystal structure, Ferromagnetic coupling
